You have 4 really good songs that you professionally recorded, hold on to them for a while until you figure out what is the best way of releasing them, because hardly anyone buys songs from itunes now, CD's are on the way out, Spotify as mentioned is great for the listeners but lousy for the musicians 0.0006 cents for each play. But with blockchain technology who know's what opportunities for singer/songwriters and musicians etc might end up being available in time. Glad your not rushing into things :)
