Audiophile, not really. Musicphile, definitely. I just checked the properties on my PC. My main music player has 6,563 mp3s inside 812 folders. My secondary player has another 35 bands with multiple albums, so maybe another 150 albums worth. I also have stacks of CDs, and a busstub full of cassettes (100+). Both my wife's and my car have working cassette players. I also have a Sony mp3 player with like another 4gig or so of music on it. Plus I listen to Pandora on my phone when I'm not at home or in the car.
As for playback, I'm with Uncle Larry. I'd rather hear music on a crap system than not hear it at all. That being said, my PC was purchased with the sole intention of being a music player, so it has a 6 speaker surround sound setup. All headphones and earbuds I buy are Sony. Yes, I like Sony.
My collection is a bit of everything. Rock, rap, metal, disco, classical, electronic, jazz, soul, funk, techno, Latin, country, blues, soundtracks, blah blah blah. Music is my drug, and if I don't hear it everyday I don't feel right.
