Well, apparently you can “measure” how “mainstream” your music preferences are (relative to the Last.fm community, of course) by following this simple formula:
Add up the total number of last.fm listeners of your top 10 artists, then divide by 10. Divide that number by 248,919 (the average of the top 10 on last.fm) to get your mainstream percentage.
So, without further ado, here are my results:
01. The Normals = 552
02. Sufjan Stevens = 111,594
03. Hammock = 1,208
04. Linford Detweiler = 82
05. Shane Barnard = 493
06. Derek Webb = 979
07. Switchfoot = 49,390
08. Nickel Creek = 12,958
09. Jars of Clay = 11,699
10. Sean Watkins = 460Total = 189,415
Verdict = 7.6% mainstream
Not too mainstream at all, eh? Of course, I should probably install that Last.fm iPod plugin so that my “most listened to” artist list will be more accurate.
