As I tend to listen to my empeg on Random or Least Often Played, the only person who affects the plays listing in any significant way is my 2 year old son. So here's my top ten list:

Chop Suey - System of a Down - 82
Too Bad - Nickelback - 67
Points of Authority - Linkin Park - 62
Blurry - Puddle Of Mudd - 62
Toxicity - System of a Down - 48
Science - System of a Down - 43
She Hates Me - Puddle Of Mudd - 39
How You Remind Me - Nickelback - 38
Child In Time - Deep Purple - 33
Smells Like Teen Spirit - Nirvana - 31

There is some Korn, Filter, Metallica and other assorted heavy stuff around 20 plays, but almost all the others are down below 6 plays each. I guess he takes after me and likes rock
