I'm working mainly for indie developers and their haven't so much money like konami.
Agreed - hence my statements "Now granted this is for AAA ranked titles usually. Indie audio is (and can be) something completely different but I'd wager even just $100 per minute of music for exclusive rights is awfully low."
If charging $100 per minute of exclusive rights fits your current business model and needs then go for it. I was simply pointing out that it is not the industry norm for exclusive rights to music - even when dealing with indie projects.
