Yes, sort of. You'd have to change the track it plays using the multi tool and unfortunately music files take up a lot of space and to be player usable the tracks would need to be duplicated taking up more space.

Would we be able to keep it to just the music it already has? Is there a duplication difference between the POI's and a player base?

The files would need to be duplicated, thus taking up double the storage space in the scenario.
