An algorithmically generated visualization based on statistical information provided by Last.fm software, more particular every song listened to by a particular user over an 18 month period of time.
Each colored band represents a musical artist, progressing left to right. the span is wider when listening was more frequent, & skinnier when it was not. the hue of the artist represents the time of the first listen for the particular user: cooler colors represent artists who have been listened to for a long period of time while warmer colors represent artists who are more recent in the user's listening habits.
"while this is interesting to look at, it is more significant on a personal level. when viewing your own music listening history you are reminded of past events that caused the trends to emerge."
