You can release music by as many different artists and labels as is necessary on your one AWAL account. Your agreement isn't exclusively for the release of one artist's music only.
Our article New Music by Different Artists goes into more detail about this.
If you do find yourself needing a second AWAL account, for example because you need to have separate accounting, you can apply for another account. Being an existing AWAL account holder doesn't prioritize the application unfortunately and it will be subject to our normal curation process. For this reason, the application form should be filled out fully as though it were your first time applying.
Application review can take several weeks and you will be notified by email once a decision has been made. Please allow this time frame and keep an eye on your spam/junk folders in case the email is automatically filtered as junk.
