I kind of like the approach
Granted, I haven't been interested in much lately, but for those who are they get 3 songs from a band rather than 1
Of course, I guess 6 would be better if you're into the band, but I like the idea: a handful of songs from a given band each week.
I am a HUGE Yes fan, and two of my favorite songs off of Fragile are "Heart of the Sunrise" and "South Side of the Sky." I can't see either one making the game if Yes got 1 or 2 DLC songs.
