I don't really care for the idea that groups should make English versions to cater to the English speaking audience. If the group cannot make their breakthrough within the western audience with their original tracks, I'm pretty sure that songs sang in (often) broken English wouldn't cut it either.
I tend to find it hard to listen to alternative versions anyway, if I've already gotten used to the original. It's just disorienting, so I usually just have a couple listens and then go back to the original haha.
