[bcasey25raptor]

pink floyd, tool, opeth, or wintersun.

Fahrenheit Fair Enough by Telefon Tel Aviv - good for testing electronic music as it's full of deep bass, squiggly sounds and warm synths that woosh around in stereo.
 
Then I usually put on some Michael Jackson

Whatever my mouse hovers over when I load up foobar.

It's either Kenny Rogers "the Gambler" or Foreigner "I wanna know what love is"

 

[Minh3184]

'Lover, you should've come over' by Jeff Buckly usually gets first dibs. Then it's Eric Clapton's 'Miss You'. Electro, Rn'B Soul and Clasical in that order next.
