This tool calculates your 'Unique Tracks Listened (UTL)' and 'Song Repetition Index (SRI)' based on your Last.fm profile. These are an indicator of how active are your music listening habits. A high UTL and a low SRI are an indicator of active listening habits. See here for a detailed explanation on this.

Enter your Last.fm username (for ex. 'kurtrips') and press enter to calculate your random song statistics.

Note: This can take a fair bit of time. The longer you've been on last.fm and the more songs you have listened, the more time it will take. This is because processing for an average user would take about 50-100 requests to Last.fm web service but they allow only 5 requests per second.

Note: If you come across a bug or are unclear about something, please see here first. Or if you like the tool want to discuss anything about the tool, join this last.fm group.
