About 2500 everything included. Approx 800 CD's and 100 cassettes. The rest consisting of LP's and 12" Singles. I've never had any desire to collect 45's . Everything is in alphabetical order and entered into a database I wrote using MS Access. I have to use a database as it is sometimes hard to remember where a specific song is located. Most especially when I've had too many Chimay's. I don't have things subdivided into genres as some do. I've never divided my listening that way. In one session I'm apt to play anything from Patsy Kline to Rufus Harley using Spooky Tooth as a segue. Yes, I also have an awful lot of recordings where sometimes 2 or even 1 selection is the only thing worth listening to. Newer material seems to have more of a problem with that. I am still actively buying vinyl and there is less of the one listenable selection syndrome with it.
