Certainly, music being played at arenas – particularly pre-recorded music – could easily be measured, rather than still being modeled. For example, a Shazam-like listening device could be deployed to capture which songs are being played in real time.
In this manner, artists would know precisely when and in what context their music is being used. This would not only allow for artists to have better information, but for venues too to be able to have a better sense of the precise cost related to their music use.
