I'll listen to pretty much anything as long as it isn't country or metal or Lady Gaga or Miley Cyrus, most popular music these days. Ick. I'm a big fan of songs I grew up with (90s/early 00s), I tend to stick to them.
"Can You Feel the Love Tonight" is totally needed anytime you are in a PuG with morons. Its the only way I got through my ToC pugging days when my schedule didn't fit with my guild's raid schedule.
And Darren Hayes... /swoon. Loved him since Savage Garden.
