As many as you like!

Within your RouteNote account, you can upload music using as many artist names as you wish.

RouteNote accounts are built to allow artists and labels to use a single account to upload their full catalogue or even catalogues under different aliases.

If you are uploading on behalf of multiple artists or running a label, you must ensure that you have the full permission from each artist to distribute and collect royalties on their behalf.

Feel free to get in touch with us if you have any questions or concerns!
