I listen to lots of radio. Mainly jazz. Here in the NYC metro area, we have two jazz stations, one full time, and the other 16 to 18 hours a day. I like radio because it keeps my mind active. I try to figure out who's playing on any given recording at any time. Many of the saxophone players I can figure out, so I move to the other horn player(s), then to the piano, bass, and drums. Same deal with singers and large ensembles.
I also appreciate having to listen to music that I don't like. And I get lots of that on the radio. I try to figure out what's bugging me about the piece, and try to determine if I'm coming from a closed minded perspective, or is it because this is a truly bad piece of music that I'm listening to.
I make it a rule to play at least the melody of the last tune playing on the radio when I turn it off to begin my daily practice routine. I've been starting on flute lately, so this is really challenging. I can't rewind the radio, so it forces me to retain as much info as possible while it's playing. Good for ear training. Todays tune was Michel LeGrand, 'Watch What Happens'. Key of C.
