Stumbled across this earlier today - a site called Dizzyjam.com They provide a service (for free) whereby undiscovered musicians can get their music distributed by attaching it to merchandise (shirts, mugs etc.) In this day and age musicians make very little from downloads etc. unless you are a well known artist. By attaching your music to a physical product - let's say a T-shirt with your logo or artwork or whatever on it, you are able to earn more than you ever will with Spotify etc. The customer gets the garment or item plus a copy of your album/single or whatever. A clever idea - and it's free. What more could you ask for?
