You will soon be able to buy music related items such as instruments, strings, picks, amps, effect pedals and songs etc with MIT Musical Instrument token, my project on top of Sirius. So then you can buy MIT with BTC and do what this thread was about indirectly through an exchange.
I will also be giving away 200k MIT (20% of total) for FREE to musicians and industry related professionals.
