As the title states, does anyone know of a good service (free or reasonably priced) that provides access to music downloads? Currently I am using Spotify, but would like to actually download the music as .mp3. Before that I was using the Firefox add-on "Youtube to Mp3" in which the youtube video was downloaded and the audio extracted. At first it was a decent method, a bit more taxing that I would like, but it eventually got to the point where most popular songs were unavailable.
