What is your source for discovering new music?

I am a VMPS speaker owner/agent since buying the speakers and have many listeners over to hear them. They bring their music, much of which is both excellent sounding and good music. I then go on Amazon.com and order them up on cd. Also, I ask the guys and gals who buy and sell equipment from me what some of their favorites are and I often buy what they recommend and sometimes their picks are awesome in every way.

Have a party and let everyone take turns playing their iPOD

Last fm, googling for internet radios, and recommendations from guys on forums.

-Agon Forum
-The back of Sterophile and The Absolute Sound
-Equipment reviews
-Independent Radio stations
-You Tube
-Austin City Limits
-iTunes (also used to sample along with Amazon)
-My employees

I used to catch new (to me) acts on Saturday Night Live and David Letterman, but it seems that my tastes have changed and/or the material there has gotten kind of stale.

I've never had much luck buying records without ever hearing any songs on the LP or cd. So, I stay away from cd and LP bargain bins unless I'm familiar with the title, no matter how much I'm familiar with the artist. That's why Pandora and internet radio has been such a boon for me. I get to hear the songs first. Oh, and I forgot the Rhapsody music service. Rhapsody is phenomenal, it allows me to choose the artist and title and listen in its entirety before I purchase.
