What is your source for discovering new music?

Buying used Cds from the bargain bins using All Music Guide as a reference.
I go through the large junk bins at several local stores and the CDs are all $1/#2. Pull anything that seems interesting. then check it in All Music Guide. Buy the clean ones with good ratings. Some stuff i am not crazy about, and a lot i enjoy.

weird thing for me, is when I search for a jazz title on Amazon.com I will then view the "what other people bought in addition to this" (or whatever it's called)and I see other titles and get to listen to snipets of them.. I have bought several cd's that way of artists I was formerly not familiar with. BTW I am mainly an LP guy.

local college radio station WIDR and internet radio WFMU

I often buy more than a CD each week...

Xiekitchen, yes, Amazon does have a nice way of offering other selections. Nice too you can listen to snippets of the selections most of the time.
