You can download music to be listened to within Spotify when you have no internet connection. It's a Premium feature. 🙂
But you can't download music from Spotify to be listened to elsewhere, like your portable media player or whatever. Well, actually everything is possible, but it's simply not legal.
I guess if you want to have Spotify on your flash drive so you can plug it into another computer, that would work. First you download your playlists for offline listening, then you can copy your Spotify folders to the flash drive. On another computer you can open up your flashdrive Spotify and I'm pretty sure your downloaded playlists are there as well.
