The audio player apparatus comprises input means (10), such as buttons (11, 12, 13, 14) or soft-buttons on a touch screen, for inputting the presence of at least one user at a location of said audio player apparatus. The player apparatus (1) further has input means (20) for preferred audio-preferences. Thus audio being reproduced by said audio player apparatus (1) is adapted to the current audio taste and/or mood of users present at the location of the audio player apparatus (1). ## Claims ### Claim 1 A player apparatus comprising: an input device that is configured to identify a presence of each user of a plurality of users at a location of the player apparatus, and to identify a playback mode associated with each user, a storage element that is configured to provide preferences that include likes and dislikes of each user, and a control element that is configured to select content material to be played by the player apparatus based on the preferences of the plurality of users present, wherein the control element is configured to select the content material, such that, for each present user: if the playback mode of the user is a first mode, the selection of the the control element functions to prevent selection of content material that is disliked by the user, and if the playback mode of the user is a second mode, the selection of the content material is based on the likes of the user. ### Claim 2 (depends on 1) The player apparatus of claim 1, wherein the input device includes a set of buttons, wherein each button is associated with one or more users of the plurality of users. ### Claim 3 (depends on 2) The player apparatus of claim 2, wherein each button is configured to indicate a state associated with the one or more users. ### Claim 4 (depends on 3) The player apparatus of claim 3, wherein the state includes: a first state indicating that the associated user is not present, a second state indicating that the associated user is present and the playback mode is the first mode, and a third state indicating that the associated user is present and the playback mode is the second mode. ### Claim 5 (depends on 1) The player apparatus of claim 1, wherein the input device is configured to indicate a preferred genre/mood of the material to be reproduced by the player apparatus. ### Claim 6 (depends on 1) The player apparatus of claim 1, wherein the preferences include volume, bass, treble preferences. ### Claim 7 (depends on 1) The player apparatus of claim 1, wherein the input device is configured to provide an indication of how strictly the player follows the preferences of the plurality of users. ### Claim 8 (depends on 1) The player apparatus of claim 1, wherein the the control element includes recommender technology means for selecting the content material to be played. ### Claim 9 (depends on 1) The player apparatus of claim 1, wherein the player apparatus includes portable audio players, car audio equipment, internet radios, or digital jukebox devices. ### Claim 10 A method of playing content material on a playback device that is configured to select the content material based on preferences of a plurality of users, the method comprising: receiving an indication of a presence of each user of the plurality of users, and receiving an indication of a playback mode associated with each user, and selecting content material for playback based on preferences that include likes and dislikes of each user, such that, for each user: if the playback mode of the user is a first mode, the selection of the content material that is disliked by the user is prevented, and if the playback mode of the user is a second mode, the selection of the content material is based on the likes of the user. ### Claim 11 A computer-readable medium having embodied stored thereon a computer program for processing by a computer comprising a code segments for playing content material based on preferences of a plurality of users, the code segments comprising: a first code segment enabling determination of a presence of each user of the plurality of users, a second code segment enabling determination of likes and dislikes of each user, and a third code segment enabling selection of content material for playback, such that, for each user: if the playback mode of the user is a first mode, the selection of the content material that is disliked by the user is prevented, and if the playback mode of the user is a second mode, the selection of the content material is based on the likes of the user. ### Claim 12 (depends on 1) The player apparatus of claim 1, wherein the control element is configured to select only content material that is liked by all users in the second mode. ### Claim 13 (depends on 1) The player apparatus of claim 1, wherein the control element is configured to select only content material that is liked by all users in the second mode, and not disliked by any user in the first mode. ### Claim 14 (depends on 1) The player apparatus of claim 1, wherein the control element is configured to select only content material that is not disliked by any user. ### Claim 15 (depends on 10) The method of claim 10, including selecting only content material that is liked by all users in the second mode. ### Claim 16 (depends on 10) The method of claim 10, including selecting only content material that is liked by all users in the second mode, and not disliked by any user in the first mode. ###
