I consider myself fairly ignorant about music. I like some music a lot, but I don't understand it — I just enjoy it. Here are some favorite composers and performers.
Romantic: Rachmaninov, Tchaikovsky, Chopin, Dvorak
Baroque: Bach, Albinoni
Soul & R&B: Stevie Wonder, Van Morrison, Smokie Robinson, Aretha Franklin — all Tamla-Motown stuff from the 60s/70s
Light pop/rock: Mariah Carrey, Whitney Huston
Show tunes: Gershwin, Porter, Berlin
