Like I said, I don't have a single favorite that I play, but when I do jam, which I try to do for at least an hour a day, it's a guarantee I'll include at least a few of these:
Nirvana - Lounge Act, On a Plain, In Bloom
Metallica - Battery, Of Wolf and Man, The Outlaw Torn, Fuel, Master of Puppets, Dyer's Eve
Anita Baker - Sweet Love
Pseudo Echo - His Eyes
Shivaree - Goodnight Moon
Alice in Chains - Nutshell, Would, Godsmack
Stone Temple Pilots - Interstate Love Song, Big Empty, Plush, Sex Type Thing
Smashing Pumpkins - 1979, Bullet With Butterfly Wings, Zero
White Zombie - Black Sunshine, Welcome to Planet Motherfucker/Psychoholic Slag
Soundgarden - Burden In My Hand, Outshined, Fell On Black Days, Spoonman
Rollins Band - Tearing, You Didn't Need
Sacred Reich - The American Way
Skid Row - Monkey Business, Youth Gone Wild
Heart - Magic Man, Little Queen
Ozzy - Bark at the Moon
Plus whatever new songs I might currently be into. Back when I first replied to this post, it was the new Stone Temple Pilots song, Meadow. Right now, it's The Hit Man by Ethan Brosh, which came out in '09 but I only heard for the first time recently on B-Movie TV (and yesterday submitted a tab for
).
