Rihanna LOUD album too soon?

[revolver8]

I was very surprised to learn that rihanna was to release her 5th studio album less than a year after her previous. I think as an artist you should let your fans enjoy your music for some time and just let them miss you which actually builds anticipation and ultimately success for your next work,i like rihanna but i think she's shoving her voice down our throats. Beyonce started way before her and has only 3 albums...and you wonder the difference in their achievements
