A customizeable greeting music whenever you join a voice channel

It would be like a 10-15 seconds sample that you could use, with the same ol' upload scheme, or you could even maybe cut it inside discord, or get the sample from spotify or youtube? 
Just something that me and my buddies thought about, one of them wants a Dark Souls boss music when he joins lol

ps.:maybe make it non spammable pls, i don't want to ban people
