Sonic Team "Power Play" makes the list because it has several Sonic things included in the compilation, and he's on the back as well. The cover is a kind of blurred mix-up of screenshots from the various games' music it features. The CD says it's "Best Songs from Sonic Team", but it seems more like "Most Overused Songs of Sonic Team". Probably since this CD, the songs seem to show up in nearly everything ST does. Not sure how they're getting away with 3 versions of the same song.
The interesting thing is that it has a hidden track of "Open Your Heart" from Sonic Adventure, which places this CD's date right before SA revolutionized Sonic.
