the top artist/artists would ahve to be Usher...Usher has had many successful albums over decades he's been singing since he was 9. PLUS JE is an enitre group.. of 4 people...to even put them againt Usher,shows Usher is obviously major competition... and *NEWS FLASH* Usher recently clenched the record for the most sold Records in a single week... i dont know how you all see it,but having the number one album and most sold in a week.. kinda shows obviously Usher is the BEST!
