@Gorilla: I prefer to use ready-made backing tracks (be it self made with BiaB or store bought) on gigs. Though it is true that BiaB gives small changes every time a song is generated, the audience will never notice since you usually don't perform a song more than once on a gig. With the pre-recorded tracks you are much more flexible to make playlists on the fly when you're using a laptop, you don't have to take hardware synths you might want to use. You don't have to wait until a song is generated. Also it is much easier to take an iPod, mididisk or even a cd with all the backing tracks as a back up than having to haul another laptop with you.

So, just for singers who use " fixed songs" I think it is best to take ready-made tracks. If you are playing an instrument (with or without other musicians) then BiaB can be the preferred way to go. With BiaB you are more flexible regarding the key a song is in, the tempo etc. You can even jam with it. Different concept.

Regarding the copyright of the backingtracks on the site I mentioned: You have permission to use the tracks on gigs (rights for the trays are with the site's owners). That's the tracks. For the performance of the songs (rights are with the owner of the actual song) in a public area rights (most often) should be paid. Here in the Netherlands most, if not all, public places (bars, clubs, dancehalls or whatever) have a deal where they pay a certain amount of money to cover all rights regarding playing and performing of music.

RealBand is a DAW: a program capable of recording and editing sound. RealTracks are bits of music played by actual musicians on actual instruments. These bits are processed by BiaB or RB to generate music tracks that follow the chord progressions the user made.
