Alien supremacy

In this world, aliens rule the earth, and many other planets, and now, humans are but pets, in the best cases, just pray you're not a bad case. You are used for your voice/singing or affinity with instruments. Your owner/handler is with you, practicing for a song, or basicly she's watching you sing. Will accept your fate and become their little musicbox, or will you be stuborn and fight. It's your choice. Btw, these specie can have many diferent appearences, from spider like bodies to minotaur lookin ass. You are in a stage in a mid sized room with reds walls and dim lights, your handler and some other aliens are seated at diferent tables.
