Method for restructuring audio within an audio file

A method for restructuring of audio within an audio file selection, the method comprising:

• a) creating arrangeable music for a musical composition stored as an original audio file;
• b) creating a plurality of custom arrangements of the musical composition, each custom arrangement of the plurality of custom arrangements being tailored to any combination of a location where a custom arrangement is to be played, a day of the week when the custom arrangement is played, an assessment of crowd participation, activity that a user is engaged in, and an assessment of an emotional state of the user;
• and
• c) providing on-demand the custom arrangements to the user for execution, wherein steps a), b), and c) are executing by a remixing/restructuring system that includes a backend computing device such that at least one of steps a), b), and c) are at least partially executed on a backend computing device wherein creating the arrangeable music data comprises:
• loading audio file(s) into computer memory by an arrangement producer agent, the audio files optionally including associated stems;
• loading alternate versions of the original audio file when there are multiple files into computer memory by a producer agent;
• batch querying database for information regarding danceability, mood, or energy, at particular times of the original audio file and associated the information with the original audio file;
• setting initial audio section fields as “intro” and “outro”;
• defining additional section fields by the producer agent as a linked list, or another data structure that identifies a predecessor and successor for each section, a combination of initial audio section fields and the additional section fields being characterized as start, middle, and end, where start sections have no previous section, but have a subsequent section, middle sections have both previous and subsequent sections, and end sections have no subsequent section, but have a previous section;
• creating audio section field transitions;
• and
• applying subjective song information from previously described database query to song sections based on times.
