Rihanna:
Rude Boy, What's My Name? (feat. Drake), S&M, Fading, Complicated, You da One, Where Have You Been, Talk That Talk (feat. Jay-Z), We All Want Love, Drunk on Love, Roc Me Out, Farewell, Fool in Love
well damn...
Honestly, I prefer her as a song writer and even with her own songs I imagine other artist singing them.
Have you guys heard Love Suicide by Tinie Tempah and Ester? It's good but... the chorus sounds like it was written for someone else (Rihanna, Emeli, or another UK girl).
She has a unique voice but unless she finds here lane I do not see her being taking seriously...All she needs is a stylist and backing from her label and I honestly think she could smash...
