JoeRugby, just so you won't feel alone, I'm also coming out as a big fan of classical music to model by. I tend to listen to music from an era a bit earlier than you, as I'm more into Baroque music.
You can sate your Baroque musical interests for really cheap, too. Here are two prime examples:
1. Everything Archangel Corelli (1653-1713) ever wrote, or might have written (there are a bunch of works attributed to him) is available in nice, historically-informed performances by the original music band Musica Amphion. You get all 48 trio sonatas, all 12 solo sonatas, the 12 concerti grossi plus about 10 other works on 10 CD's. CD Universe carries this set for a piddling $37.89.
2. If you're just starting work on, say, a multi-media battleship kit, you might want to consider all 555 keyboard sonatas by Domenico Scarlatti (1685-1757). Pieter-Jan Belder has been working his way through them for the last several years. He's just released volume 9 (out of 13 volumes = 39 CD's). This 3-CD set contains the sonatas Kirkpatrick numbers 372 through 427. Belder plays a variety of harpsichords, organs and fortepianos, and plays all of them very well. CD Universe carries each volume at around $10.00 per volume. I figure that volume 13 will arrive just in time for attaching the last PE fiddly-bits and rigging the beast.
