I once bought a 2Pac CD at the same time as an Alanis Morissette one. That confused the clerk a bit.
No love for the Scorpions, JT? Their non-80s stuff is generally quite good, even if their output from that decade is a bit "hairy."
BCJ, you should listen to the very first Chicago album. It's like a totally different band from the stuff they've done since; very jazzy in a "real" jazz way, not a smooth jazz way. (Speaking of which, JT, did your Pandora station play any of Miles' more experimental later stuff? I dig his earlier stuff, but I love when he started getting wild--y'know, the rock/funk/jazz stuff most people seem to hate.)
