Can someone please come and talk to me about buying classical music!

[DANCESwithLordPottingtonSmythe]

I want to buy a copy of Mozart's mass in C minor. I've just had a look on Itunes but there's lots of different options, how do I know which version to buy?

There's no right or wrong answer to that: if you have time, listen to a couple of excerpts from 2 or 3 different recordings )(preferably the same excepts from different recordings), and go for the one you like best. Or if you hear it on the radio, find out the conductor and orchestra.

Which ones has iTunes got?
