Confused About Spotify

[deadwrong03]

Im checking this app out now since it just came to Windows Phone 7, and it says you can upload your personal library to spotify

so if im uploading all the music on my laptop is it stored in like a cloud where i can listen to what i want when i want? or is it to help spotify shuffle the tracks in their own collection and go through them like pandora?

i signed up for the free spotify to try it out and im trying to sync my library with spotify and im not sure if its syncing properly is there somewhere in the app that lets me see what ive synced?

what exactly is the difference between spotify, google music, pandora, slacker radio, and last.fm???

is spotify a way for me to have all my music on my computer backed up to a cloud without having to have it take up memory on my phone?

They were just talking about it here: http://forums.windowscentral.com/marketplace-apps/182902-2.htm That may give you some insight.

If you are using the trial offer, it doesn't last very long.

Spotify allows you to sync your songs to your device and will use those songs over the streaming versions if you're on the road.
