I have yet to find a genre that I always enjoy, or one that I never enjoy.
In the car I nearly always listen to hot jams on the radio. It's redundant, overly produced, and predictable which means that it doesn't distract me or overwhelm me with emotion. When I have a music player in the car I tend to become obsessive about it, wanting to listen to just the right thing at just the right time - interrupting one song to start another that strikes my fancy. If I'm the driver it's not safe, like texting. If I'm the passenger I end up driving everybody else crazy with my pseudo DJing.
Otherwise I am equally as weird about music. With exception of a FEW kids songs (ABC, twinkle twinkle, row your boat...a few more), I do not know all of the words to any song. Not even my favorite ones. My husband gets a kick out of correcting me when I try to repeat song lyrics. I always, always, always screw them up. Ditto proverbs and common sayings. I get the point across, but never the details.
Anyway, point being, the melody and rhythm of music is incredibly important to me. And then, when I really love a piece of music, it completely overwhelms me with emotion. It's intoxicating. Sometimes I go days on end without listening to 'my' music, because it is so moving and it stays with me.
And I have phases. Sometimes I will listen to two songs over and over and over, or one composer/artist, or one album, or one mix. Usually, I have it just so and then, suddenly, it becomes time for a change. It's funny, there are some pieces that are like a time machine because I will have listened to them so much but only for a phase.
Right now I am in a big time Chopin phase. I've cheated on Chopin a few times to listen to Nina Simone's "Ain't Got No" and Nancy Sinatra (and Lee Hazelwood), Leonard Cohen, Cocatue Twins, Johnny Cash, David Bowie, Sigur Ros, Cat Power, Nick Cave, Pavarotti - I can't think of any others right now. Eric Satie is almost always agreeable, at least I can always listen to "Gymnopedie".
