Most music artist are already tired of spending money on music promotion and distribution
Because most of them never get to see any promised royalty.

The 3rd party submission is not working

But I will suggest you try tunezsell.com

Where you upload directly
And be in control of your account

You get to monitor everything happening on your page via your Artist dashboard

You can also withdraw your royalty and get paid in 24 hours.

Tunezsell does not distribute to any platform it is a stand alone streaming platform that help you monetize your music fast .
