One thing that really inspires me these days is on-line radio, such as Pandora, GrooveShark, or Dizzler. We live in an area with a fairly limited number of radio stations, and though I like a couple of them, the online outlets allow me to select from a broader range of music. Generally, I log onto to pandora.com, to access one of several stations I am building for myself. I have one just for studies with baroque style music, but I also have an old-school punk station and some newer alternative on another just-for-me "station."
I also like logging into a band's myspace page and listening to whatever they are streaming there. I've got a little Spoon playing right now... very unproduced, pretty low key, perfect for my evening of cooking and taking it easy.
What inspires you... musically speaking?
