Yes, you can upload a cover. A cover song is a song that you performed & recorded yourself, but the music was written by someone else. A cover song is a straightforward interpretation of an track and no significant changes have been made to either melody nor lyrics.
How do I correctly upload a cover in the app?
It has to be your own recording. You must fill in the original writers as writers.
You may NOT mention the original artist (or the fact that it is a cover). You can't have it in the release text nor on the cover art.
Do I need a license?
You only need a license for selling downloads of covers in the US, Mexico, India and Pakistan. If you decide not to purchase a licence then please deselect these countries in the countries selection in the app. IMPORTANT! (The reason for this is that all countries except these four have agencies that collect royalties for the writers).
Where can I get a License?
When it comes to licensing, we frequently see our users using songfile.com (we are not affiliated) but there is a great deal of information about the service they provide on their site.)
Can I translate the lyrics for a cover?
Yes, but you need permission from the copyright holder. When you make a substantial change to a song, like a translation of the lyrics, you need the permission of the copyright holders as it is regarded as Derivative work, and not a cover.
