The whole song without any protection would be easy to record, so that's not going to happen.
But for future songs I will go back to the short but not watermarked previews. Thank you for pointing that out!
That's also a good call as a seller who composes music as well. I'm considering only putting out 10 to 20 second previews on my main website to stream since Soundcloud may be losing money soon:
