How to make money from music:
A TED talk from Amanda Palmer, entitled "The art of asking"
Amanda Palmer is a musician, who, amongst a lot of other things, made over 1 million dollars on Kickstarter
And then gave her album away - FLAC version was donationware IIRC; 320kbps mp3 was a free download.
Topicwise, you may find the talk a bit slow moving initially, but it's well worth sticking with.
Oh yeah, it's very slightly NSFW at times (but not in any exciting way :p)
