Maybe like, $300 or so. I used to get a good amount of albums back in the day and I still buy some digital ones on iTunes. I also gift a lot so that's definitely a contributor.
Well I have around 40 CDs, let's just round the individual price of those to $10 to make it easy so that would be $400, then I purchased ~25 songs on itunes for 1.29 each so let's just say it's somewhere near $450
