Easy

its easy. release it on bandcamp. you can sell a cd-r with it, or on tape. many release professionaly on vinyl even. you can make 1 song be playable then the rest only IRL. or just play it only IRL at shows. its the ultimate way to experience music. the best mastered / mixed track ive found is sinead oconnors "sacrifice". it only really works with headphones or on a good stereo, because of the divergence in the singing strength. this can only really be found while listening live otherwise. if you have nowhere to play, look around for a local radio show / channel. send it around to places. say youd prefer to perform it vs them just playing it. in stockholm i found radio totalnormal. but theres tons of them. some only online as well. or just buy a boombox and play it outside in the grass or the beach or out your window. make people enjoy your music. thats what its about.
