While I generally consider myself to have eclectic musical tastes, the amount of classical music in my collection is very low. There is a bunch of Mozart, some Grieg, and a bit of Rimsky-Korsakov, but nothing to write home about.
This is one of the reasons I am excited about the BBC's Beethoven Experience (via Legal Tags). All nine of Beethoven's symphonies will be broadcast on the radio, and are then available for free download in DRM-free MP3! Symphonies 1 and 3 are available for download right now.
