Been using a service named Globex Music for a long time, and overall I’m pretty happy.
The upload process is simple. No confusing steps.
Approval time is good. In my case about 24 hours. Sometimes a bit longer, not a big deal.
Customer support is responsive. Maybe not 24/7, but they help.
Getting paid is simple. Pretty standard process.
I upload both original tracks how to get on youtube music as an independent artist and covers. Covers also work fine.
No hidden payments. Just pay per release.
Everything is ok overall.
Feels like a small platform, but ok in practice.
They also have a partner program. You need to contact support.
In general you can try it yourself. Of course not ideal, but works fine.
Also, feel free to check my music.
