Okay - I am in the much older age group. LOL Before Television was in every home, my home, at least played 78s featuring the big bands along with jazz. In the evenings we would listen, dance and play games - after homework, of course. Then in junior high we discovered 50's pop and 45's became the record of choice. I loved all the goofy songs such as "Pink Shoelaces". Then by high school, the 33rpm and the album became popular - as well as American Bandstand on TV (every afternoon at 4:00 after school let out). The dance songs became more edgy with Elvis and Bobby Rydell. Ah...then the revolution that took place when I hit college in 1964...the Beatles, the Stones. That is the evolution I went through and I continue to evolve today.
While I've never been able to listen to rap - admitting I haven't tried hard enough - I have committed to everything from classical (because I sang in a choir and came to appreciate it from that experience) to the hard rhythms of metal to an extended period with country. What really brought me back to rock was Dilana during the Rockstar show. Since then I have gone looking for rock to download, though I mostly stay in the alternative section - I discovered Regina Kaplan after a segment done by the CBS Morning Show and now have all her quirky songs.
I guess my experience says to keep you ears open and you might find gems in whatever trend is popular at that moment in time.
