DIstributing my music on the internet, what is the best and why?

[Ramy Moustafa Saber]

Hello all:
AM thinking of producing my music over the internet, so, what is the best
distrokid, cdbaby, tunecore, or what?
I read many articals, and i can understand that distrokid is the cheapest, but i must use another tool called song trust to protect my royalties, is this right?
but am asking here about the accessibility,
if anyone tried the distrokid, please tell me.
thanks
