Exclusive music is better, no?
Yep, it is! I've just grabbed a track after listening to literally hundreds over the last few hours, cost me under £20 in the end.Still need a track for the front-end and an alternative in-game one, as the one I've chosen is very 'ambient'. I found that faster music tends to get distracting in games like this.
SonicFactory: Catch me on IRC sometime - royalty offer as discussed previously still stands. Or I can paypal you a few quid if you prefer.
