Kickstarter is just one platform. I could see this inspriring a hacker/musical artist to build a Kickstarter-like platform specifically for musical artists to raise capital for new albums and connect directly with fans. I could also see that same website providing a ticketing platform where people could back a show in a specific city to try to get an artist to come to their hometown instead of selling through TicketMaster and having scalpers buy up all the inventory.
Also, even with platforms like Kickstarter or payment processors like Stripe, the important thing is that the artists retain the rights to their songs, instead of the record labels purchasing them through investment. I've heard that most artists make most of their money off royalties from 2 or 3 hits songs.
