I think if they are a good singer who can interpret material well, it’s great. I mean look at Dolly Parton and Whitney Houston — they both performed amazing versions of “I will always love you” but only one of them wrote it.
I do find it funny how most famous singers these days will claim a songwriting credit by adding one line to a tune. Gotta get that publishing credit $$$$!
Does the UK fluoridate its water?
