Show HN: Today I launched DistroKid to help musicians upload to Spotify, iTunes

Awesome service. Is there any chance of having a song rejected? If so, on what basis? I'm all for services that make it easier to get onto these services, but as the price gets closer to zero I wonder what barrier is left. Will spotify/itunes end up like google results?

I have released some songs on Bandcamp.<p>What are the benefits to being in a large marketplace like iTunes?<p>I am very intrigued with Spotify being in the mix. Keep up the good work.

I'm super intrigued, but given the services that are available to indie artists today... this sounds too good to be true. What's the catch?

Great concept. I will check this out for sure.
