you could do a modernization of music and instruments, like, put songs famous as michael jackson, new instruments, but this is my suggestion
I suspect copyright issues may arise if such songs were to be included. Looks like most of the songs included in the base game are either public domain or are from a game that Chucklefish has helped publish.
Also, music isn't that hugee of a thing in starbound, so it'd surpizing to ever see an update solely on that
