When you add a new release using Musixmatch Pro, it is very important to provide the correct album link From Spotify and Apple Music. The most common mistake is usually to provide the link to the song, instead of the link to the album or single.
Here you can find a guide on how to make sure you pick the correct album link.
Spotify
1) Search for your artist page
Open Spotify and search for your artist page.
Example: Billie Eilish
2) Select your album
Click on your album.
Example: Happier than Ever
3) Copy the link to your album
Click on the three dots >> Share >> Copy Album Link.
The correct URL will always have written "album", won't have written "track"
Also, please make sure to remove from the Url, anything which is between ".com" and "/album" when you copy the link.
Example below, remove "/intl-de":
Apple Music
