well, that's tricky. But whenever I get bored I start looking at the roots of music. Old R&B, smokey Robinson, Barry White, Marvin Gaye. Old jazz, Ahmad Jamal, spyro Gyra, Miles Davis, Dave Brubeck. Old Rock, The stones, the beatles, Eric Clapton, Cream, Mamas and the Papas, Fleetwood Mac. Old Country, Willie Nelson, Waylon Jennings, Johnny Cash. And Blues, any old blues.
But if you just want to listen to new music that you havent heard yet, search in a music download site for the music you like, and look at the stuff that the site recommends as similar to it.
There is a website called pandora, and if you type in, say, Jewel, it will take her music, and then create a radio station of similar styles of music that it thinks you would like that is sort of like Jewel. It is free. www.pandora.com try that!
I love all music
