Yeah, the Spotify catalogue isn't exhaustive by any means, but its pretty darn good. I miss some more obscure items from my mp3 collection, especially some techno/dance stuff I enjoyed in my early 20s (I shed a tear for that occasionally) - but overall I feel like the benefits of shedding a 30GB collection of files whose metadata I was obsessed by outweigh the negatives of dumping my personal music collection. If Spotify dies I'll just move onto the next service. If there are a few obscure mp3s you can't live without you can import them into your Spotify client. They'll get auto synced to any mobile devices you have connected and the client installed on too (although not cloud synced to other computers - you'd have to copy them manually). Spotify does a lot of local caching, so once you've listened to a track once it'll likely be cached so it doesn't hammer your collection too badly. Pretty sure I've continued to get good gaming pings while my gf listens to Spotify in the next room :) EDIT: I did not know about the P2P stuff. Huh! Interesting ...
