Recently I've discovered jango.com, a commercial-free radio station online. It's the best.
I was watching the TV series, "House" one night, and there was a theme song for that episode called "Are You Alright," by Lucinda Williams. I YouTubed it, as it were, a trick my 12-year-old daughter taught me. At about that same time, a friend told me how great jango.com was.
This is the way music was always meant to be discovered, I think. I quickly became an all-out Lucinda Williams fan, but jango.com automatically provides music similar to the favorites you program on your personal radio station. If you're a music fan I suggest you try this.
It's better than WMMS in its heyday. And "House," is also a pretty darn good television series.
