Geez, I have no idea how many songs my collection would house..I just don't wanna go there numbers-wise..lol.
But I would say for a pretty close estimate:
vinyl - 120 albums
cassettes - 315 give or take around 10
cds - 5,000
computer/digital - around 200 gigs..
..and of course, I'm always feeling like I just don't HAVE anything to listen to..lol!
