@OntheWindowStand,
Bob Dylan, Tom Waits, a little bit of Grateful Dead, Coldplay, Radiohead, and a lot of Indie (and related) stuff, like Bon Iver, Fleet Foxes, Shane Nicholson, Shearwater, Okkervil River, Elbow, Death Cab for Cutie, and Shiny Toy Guns. I drive 57 miles each way to work every day, so I listen to satellite radio. I'd have never discovered these bands otherwise. Listening to NPR's
All Songs Considered is my other source for new bands.
I listen to a lot of world music, especially from West Africa. No one beats Youssou N'dour, but I also love Baba Maal, Angelique Kidjo, Amadou and Mariam, Orchestra Baobab, and Salif Keita.
At the gym I'll put on thrash metal -- Metallica, Testament, Anthrax, Megadeth, Slayer. Not really my thing anymore, but I'll get a little bit more weight on the bench if I'm listening to music like that.
At home mostly classical and opera. Gustav Mahler's symphonies are almost works of philosophy unto themselves -- just beyond belief. Especially his 2nd symphony if I had to pick one. Huge fan of all things Mozart. I listen to lots of opera, especially Mozart's and Verdi's. And I love choral music.
My son, who is 10 months old, loves to jump up and down in this farm-themed jumparoo device. Rather than listening to Fisher Price renditions of "Farmer in the Dell", "Turkey in the Straw", and "Mary had a Little Lamb", we made him a mix with a bunch of breakdancing music and hip hop. Awesome seeing a baby jump up and down with a huge grin on his face with Newcleus on in the background.
