(apparently there are rules to journals >o< I wa shock da!)
Get your overall top 10 artists from Last.fm, and find the top 3 of their tracks that you've scrobbled most. Then note where it comes in that artist's "most-played" lists. The lower the track in the list, the weirder you are... or something to that effect.
okay, let's see how we go ;P
High And Mighty Color
1] XYZ [3 - because it's new and awesome \m/>w<\m/]
2] Mirror [95 - because it's mistagged (and by me DX) and awesome \m/>w<\m/]
3] Over [6 - because it's old and awesome \m/>w<\m/]
average mainstreamity: 35 = win!
1] エーテル [51 - one of her best songs ever - needs to be listened more >o<]
2] アントワネットブルー [2 - this got loads of plays when it was the only new song for a year and a half or something stupid ^__^;; still popular which is quite nice]
