Spotify offers free and legal access to a huge library of music. The free music option includes adverts, but there are also two paid-for options which don't have adverts. The one is a 'day-pass', and the other a 'monthly subscription' which allows you to download tracks in MP3 format so that they can be played even when you aren't connected to the internet.
