I have about 150 CDs, and 30-40 LPs. I have about 20 SACDs and DVD-As (don't know how many of each). I've got about 50 DVDs, although probably 60%+ are parts of boxed sets.

I really don't buy many CDs because honestly there aren't that many I actually want to own and I have trouble determining which older albums I want to buy. And then I have to wrestle with the CD or LP decision which sometimes ends up with both (or sometimes LP and SACD, etc).
