You know, if you went with Spotify streaming to find that music song you liked round there, you should know that you can also download mp3s from Spotify to the hard disk easily.
Well, not download but rather record mp3s from Spotify with some Spotify Recorder program and save 'em to the hard disk. If you want, you can try some Audials piece of software for the job, works quite good as a Spotify recorder:

U simply use it to record and convert Spotify music streaming to good quality mp3 tracks, save the recordings to computer and problem solved fast.
Just remember to keep the recorded mp3 music for personal use only, to be on the safe side.
