In the 60s an all-Chinese band toured the circuit in the western US. They played and sang only country music.

After the first startled look at them and the smiles it provoked, people settled in and enjoyed the show. They were good.

As a further thought, if 'alien' music were banned, then surely males could not sing songs from the female point of view and vice versa.

Go for it. Become the best calypsonian anyone ever heard! Or not. Not being bred to something that you choose doesn't mean that you have to be better than everyone else. Just enjoy it.
