What you should back up is the playlists, since no matter what you buy, you will never legally own the music. Sometimes it's easier to work around the DRM than other times, but in no case are you supposed to be able to make copies and I find it easier not to try this and keep hundreds of extra gigabytes around when I pay for the service to host this for me already. The music will exist elsewhere as well, from the pirate bay to youtube to other music services to CDs if need be. The playlists are the data they can keep hostage, so I back that up. When Grooveshark went offline without notice, I was lucky to have some offline songs on Android and some localStorage in the browser (and the skills to retrieve it). I don't want that to happen again, I lost quite a bit of music there, so I back this up now. At first I used a self-made a Spotify API client; later I found another tool to do this with: https://github.com/watsonbox/exportify https://github.com/watsonbox/exportify
