WILL I HAVE TO PAY ANY ROYALTIES AFTER I LICENSE A TRACK FROM ALIBI?

Everything you need to know about music royalties on ALIBI.

No, assuming you have properly licensed the music you never need to pay ALIBI again. If your video is placed on a platform (broadcast television, streaming services, entertainment venues) that has an agreement with a Performing Rights Organization (in the United States: ASCAP, BMI, SESAC) the platform or venue pays performance royalties to the Performing Rights Organization. Performing rights organizations pay performance royalties to the musician/composer/artist and to the publisher. 

There are no performance royalties on Video Games and Apps.
