Well if they're successful... then obviously there is a reason

as long as the singer is singing the songs they want and they connect to and if the music is good...then whats the issue. Also lets be honest if we only had singer/songwriters then alot of people would go hungry and a song like we found love would never see the light of day. Imagine umbrella by any other voice but the icon's? Or single ladies not by anyone but the kingbey? How boring would that music vid had been

But what if a singer can't sing or write but there albums can go platinum unlike singers who can sing and write? Explain

Clock 'em, Janelle.

This is what I'm saying people need to shut up and worry about there favs albums not able to sell

everyone can sing...you either a good singer or a bad singer... And you are talking studio vs live which is a whole other thing.

Ever heard of a fullstop? Use it.

Rihanna may be able to sing wonderfully but her inability to write a song doesn't do wonders for her artistry and it's certainly not a showcase of talent/skill.
