Here's an interesting scenario.
You record an album using Real Tracks, acknowledge the musicians that helped create the Real tracks, and release the album.
Someone compliments the Real Tracks musician on the work he did on "Bill Smith's" album.
He replies "I've no idea what you're talking about...... I do not know "Bill Smith" and I certainly did NOT work on his album."

Just a chuckle!

Cheers,
