Weird Al. ALL of it.
I like Euforquestra. Funky, afrobeat/raeggae (sp) stuff, but you can download the full SOUP album on their website free of charge.
I am also a fan of Rhonda Larson. It's flute music, but it's mostly folk tunes from all over the world. She is beyond amazing in her skill and I love the tunes, especially on the Distant Mirrors album.
The family is a fan of the Dr. Horrible Soundtrack AND the Dr. Horrible Commentary. not sure where to get them. I ripped the tunes from the DVD...
More mainstream stuff might be:
Any Best Of album.
Men at Work Cargo
Empire Strikes Back (Imperial March, Asteroid Field, Yoda's Theme, The Force(?) and of course the Main Title!) The Episode IV soundtrack is also nice.
Van Halen Any of the original albums are great. I like pretty much all of the albums except for the one with Gary Cherone from Extreme. And I actually LOVE Extreme! He just did not fit with Van Halen at all IMO.
Extreme Any of the first three albums, but especially III Side to Every Story.
Hayseed Dixie. Covers of classic rock tunes and some tunes from a couple of other genres. Covers done in Bluegrass style!
Here Come the Mummies. Funky horn-based tunes with a light touch of sexual innuendo. Ok, more like a DEEP RUB of sexual innuendo, but it's all good, baby!
Really, can't go wrong with a "hits of the 80s" collection.
Eminem. Love the recovery album and his latest MMII album. Even if you think he's a real dick, he's extremely talented. Maybe the most talented rap artist on the planet. An actual wordsmith and his last couple of albums have a real personal vibe going. He is a Rap God. (And i can't stand most rap or Hip Hop (what is the difference?)
Ok, gotta go for now. HOw much time do you have??
