Yep, just like Britney. Although hard core Rhianna fans HATE when you bring that up.
They aren't no where near as bad as Beyonce fans though when you bring her ''writing credits'' up
Beyonce fans are the most defensive I have ever come across. Its actually quite scary how far some of them go just to defend her from criticism.
At the end of the day though who cares if an artist has songs written for them? its such snobbery to take away from an artist just because they may not write their own material. Half, if not all, the songs Elvis sung were not his own! did that stop him from being an incredible artist? no it did not. So my advice, get over it!!
