Metadata informations...

In order to deliver your music to the platforms you need to follow some strict rules and guidelines!

Accurately filling in contributor information is crucial for proper referencing. There are two "levels" you need to distinguish;
"Release Level"
is where you indicate information regarding the release as a whole
the "Track Level"
only concerns each individual track.

The first key to correct referencing is consistency ensuring careful inclusion and referencing of everyone's work, at all levels. 

ARTISTS
Main artist is the primary performer of the track you release!
Artists names should always appear on the artwork exactly as listed in the metadata, with the same name, order and role.
Artists that appear on less than 50% of the tracks cannot be listed on the "Release Level" and cannot appear on the artwork.
If 3 or more artists are listed as main artists on the "Release Level", platforms will automatically categorize the release as a compilation.

RELEASE
This is is where you indicate information regarding the release as a whole.
Title of the release should be exactly present on cover as is in metadata!
