Yes, the music available on Artlist is royalty-free with a subscription. We guarantee your use of music is royalty-free as long as your use is within the terms of our license.
The following excerpt is from our license agreement:
"While our License gives you the right to perform the Projects in public, it does not cover payment of royalties to performance rights organizations (PRO).
That means that if you or your client wants to use Projects in broadcast or in other public performance platforms, you might receive payment requests. In such a case, you will need to pay (or ask the related broadcaster to pay) the amounts under such a request to the relevant organization."
