I know Lou Bega used Reason. ( He's the guy that made Mambo Number 5 ) He was the only person i knew. I know the Black Eyed Peas use there own instruments for there stuff but didn't know that they used Reason.

Liam Howlett uses Reason to create the basics of his tracks.

Who's Liam Howlett?

The man behind The Prodigy

Yes, there was an interview with him somewhere on the net. I can't find it now.

Prodigy uses Reason I believe. I think also Nine Inch Nails. That just shows you the potential of Reason.
