Holy ear buds, Batman!
Do you guys know about Pandora?
It's so cool.
Apparently, it's an outgrowth of the "Music Genome Project," an effort by a bunch of musicians and music lovers somewhere in the big wide world to take songs and break them down into their basic musical components ("vocals-centric, blend of electric and acoustic guitars, in a major key," etc.). And the way it works is you type in the name of a song or an artist you like and Pandora starts playing songs by artists famous and obscure whose genotype matches your selection.
The aspect I like the best is the "artists obscure" part. Have you heard of Hayes Carll or the Starlight Mints? Well I sure hadn't till they popped up on my personal Pandora radio station.
The downside is that if I give into my yen to purchase all this new (to me) music I'm suddenly exposed to on iTunes, I will very quickly go broke.
So be careful. Remember what the outcome was for this website's namesake.
