A user device (such as a personal computer, tablet, or smart phone) receives media elements from a media repository. The media repository may be remote. The device displays references associated with the media elements in a display area. The device outputs media content (e.g., music or video) associated with each of the media elements for a limited duration (e.g., 30 seconds). While outputting, the references displayed in the display area are scrolled. The display area may be provided as a 3D drum. ## Claims ### Claim 1 A system for presenting media content comprising: a processor; a memory device operably coupled to the processor, the memory device being configured for storing program code which, when executed by the processor, causes the processor to perform the steps of: displaying one or more references in a playlist-display area, wherein the one or more references are associated with one or more media elements; wherein the displaying comprises displaying alphanumeric information and an image associated with the first media element; wherein the references are displayed on a 3D graphical representation of a rotating cylinder; outputting media content associated with a first media element of the one or more media elements for a predetermined play duration; displaying a play-indicator for indicating the reference associated with the first media element; scrolling the references at a scroll-rate while audio is being output; the scroll-rate being related to an image size of the references and the predetermined play duration; and outputting media content associated with a second media element of the one or more media elements for the predetermined play duration. ### Claim 2 (depends on 1) The system of claim 1, wherein the program code further causes the processor to perform the steps of: displaying a first preview-speed-control button, wherein the first preview-speed-control button is selectable by a user; and decreasing the play-duration when the first preview-speed-control button is selected. ### Claim 3 (depends on 1) The system of claim 1, wherein the program code further causes the processor to perform the steps of: displaying a second preview-speed-control button, wherein the second preview-speed-control button is selectable by a user; and increasing the play-duration when the second preview-speed control button is selected. ### Claim 4 (depends on 1) The system of claim 1, wherein the program code further causes the processor to perform the steps of: displaying a preview-speed-control bar, wherein the preview-speed-control bar is configurable by a user; and wherein the play-duration is configured based on configuration of the preview-speed-control bar. ### Claim 5 (depends on 1) The system of claim 1, wherein the scroll-rate is determined in accordance with the following equation: scroll ⁢ ⁢ rate ⁢ ⁢ in ⁢ ⁢ pixels ⁢ ⁢ per ⁢ ⁢ second = [ height ⁢ ⁢ in ⁢ ⁢ pixels ⁢ ⁢ of ⁢ ⁢ reference ] [ play - duration ⁢ ⁢ in ⁢ ⁢ seconds ] . ### Claim 6 (depends on 1) The system of claim 1, wherein the play-indicator is a horizontal line. ### Claim 7 (depends on 1) The system of claim 1, wherein the media content is audio data. ### Claim 8 (depends on 1) The system of claim 1, wherein the media content is audio-visual data. ### Claim 9 (depends on 1) The system of claim 1, wherein the play-duration is within the range of 10 seconds to 60 seconds. ### Claim 10 (depends on 1) The system of claim 1, wherein the program code further causes the processor to perform the steps of: receiving alphanumeric information from a remote media repository; and storing the alphanumeric information in a reference list. ### Claim 11 (depends on 1) The system of claim 1, wherein the program code further causes the processor to perform the steps of: receiving media content from a remote media repository; and storing the media content in a media content list. ### Claim 12 (depends on 1) The system of claim 1, wherein the program code further causes the processor to perform the steps of: fading out the output of an ending portion of the media content associated with the first media element; and fading in the output of a beginning portion of the media content associated with the second media element. ### Claim 13 (depends on 12) The system of claim 12, wherein the program code further causes the processor to perform the step of: starting the step of fading in the output of the beginning portion of the media content associated with the second media element following a predetermined period of silence after completion of the step of fading out the output of the ending portion of the media content associated with the first media element. ### Claim 14 (depends on 12) The system of claim 12, wherein the program code further causes the processor to perform the step of: starting the step of fading in the output of the beginning portion of the media content associated with the second media element immediately after the completion of the step of fading out the output of the ending portion of the media content associated with the first media element. ### Claim 15 (depends on 12) The system of claim 12, wherein the program code further causes the processor to perform the step of: starting the step of fading in the output of the beginning portion of the media content associated with the second media element prior to the completion of the step of fading out the output of the ending portion of the media content associated with the first media element. ### Claim 16 (depends on 12) The system of claim 12, wherein the program code further causes the processor to perform the step of: accessing a lookup table to perform the step of fading out or the step of fading in. ### Claim 17 (depends on 12) The system of claim 12, wherein the step of fading in is performed in accordance with the following equation: fin(t)=Volume*[1.0−e−At2], where t=[T−T0]/[Tin−T0] and A=4.7. ### Claim 18 (depends on 12) The system of claim 12, wherein the step of fading out is performed in accordance with the following equation: fout(t)=Volume*e−Bt2, where t=[T−Tout]/[Tend−Tout] and B=4.7. ### Claim 19 (depends on 12) The system of claim 12, wherein either the step of fading in or the step of fading out is performed in accordance with a linear function. ### Claim 20 (depends on 1) The system of claim 1, wherein the program code further causes the processor to perform the steps of: displaying a play-order-control button, wherein the play-order control button is selectable by a user; reversing the order in which media content associated with the one or more media elements is output when the play-order control button is selected; and scrolling the references in the reverse direction while audio is being output when the play-order control button is selected. ### Claim 21 (depends on 20) The system of claim 20, wherein the program code further causes the processor to perform the step of: shifting the references with respect to the play-indicator when the play-order control button is selected, thereby the play-indicator indicates the same remaining play-duration as before the play-order control button was selected.
