Yes, that is a good one, although I use both and I'm just starting on Musicoin.
I think Musicoin can offer you more as an artist. DSound.Audio is nice too, but as with the Steemit and DTube accounts, you need a lot of loyal followers to earn a buck. Also DSound.audio does not offer you a search-option (that I know of), making it pretty hard to find songs on it. At this point my account has to be verified by Musicoin, if I know more about it I will do a review about this very topic.
