Following in the footsteps of recent, but limited, transparency from Warner and Sony, Universal Music Group has also come forward to say that, yes, it does pay breakage to artists. This marks something of a landfall in the increasingly busy and omnipresent conversation of artists' and songwriters' rights, streaming services, as well as royalties and licensing.

What is breakage? Breakage is the surplus money left over when a digital advance or minimum guarantee from a streaming service to a label exceeds royalties in any given period of time. Warner, for instance, stated last week that it has been doing this since 2009.

A spokesperson for Universal said:

"Our approach to artist compensation is designed to provide income across multiple sources. While the most significant source is comprised of royalty payments, we also choose to share with artists minimum guarantees as well as unrecouped digital advances, where they exist. For example, by the end of 2015, artists will be allocated a share of unrecouped advances from the current calendar year."

Whether or not it is treated like royalty payments, and what percentage of the breakage actually goes to artists – for they need to exist in the first place to be "sold" to streaming services, so it's only fair – is still a mystery.
