I've gone through many phases of music. When I was very very little (3?) it was mostly nursery rhymes...Old MacDonald, Clementine, Little Miss Muffet etc etc.
I think I had all 4 of these CDs from The Countdown Kids...all nursery rhymes sang by four 1st-2nd graders. Believe they were Canadian. This was the one I played the most: http://ecx.images-amazon.com/images/I/41C4XKWZCJL.jpg
At the same time, I was also getting into the relaxing format of smooth jazz. We had a local SJ station in Seattle on 98.9 and that's what I would listen to day after day. Loved hearing Peter White, Sade, Paul Hardcastle etc. AND STILL DO! Right now at the age of 17 1/2, my #1 format to listen to is smooth jazz. Most people find that "elevator music" and "boring", but I like the groovy, relaxing sound of a sax or guitar instrumental. Also enjoy the smooth R&B from Sade, Anita Baker, Basia etc. that aired on SJ stations. I would go to sleep with smooth jazz playing on the radio, instead of a CD or cassette with lullabies and Mozart pieces.
I was still mainly a SJ listener for many years, then around 2007-08 got into 60s/70s oldies, back to smooth jazz and soft rock, then a phase of modern country music over a couple of years...because my mom loved country music. Back to smooth jazz. Stayed with mostly soft rock/smooth jazz after that, but do listen to some 90s country, 60s/70s oldies, 80s pop, and some classic rock here and there. Also enjoy the throwback Rhythmic adult contemporary hits from people like Janet Jackson and Whitney Houston. Can't stand most soft rock stations nowadays...they have turned into light versions of top 40 stations. Back in the 1990s, there was a lot more love songs. Now it's the 245th place on the dial to find Katy Perry and One Direction.
Probably 99% of my high school would care less about a 2001 sax cut from Kim Waters. But that's my type of music. They would rather put rap into their car's speaker system and boom boom boom their ears out.
