This URL shortener from Apple features an interesting approach that promotes collaboration among artists.

 Here is an interesting indirect collaboration tool for Apple Music artists. Apple provides its own link shortener for the products they offer, including your artist page on Apple Music. Here is the link to the tool. 

What makes this particularly engaging is the opportunity to join their affiliate program, which we can discuss further later. You can insert this affiliate token into a shortened link, allowing you to create a short link not only for yourself but also for the artist you have collaborated with. 

For example, if you release a featured record on YouTube and wish to credit your collaborating artist or promote any music you enjoy, you can easily create a short link for that artist, include it in the description, and earn a small commission from sales and streams. 

My favorite aspect of this tool is that it fosters a more collaborative environment by encouraging the recommendation of music you love, taking a step beyond self-promotion.
