*gggigggles* Rihanna takes HUGE RISKS! I mean for her "Risk singles" she does zero promo, and refuses to shoot videos for them. Then for her pop/dance/non-risky singles, she does heavy promo, get's radio deals, shoots high budgeted music videos.
Honestly, i don't see it being a "RISK" if all the "risky" singles she's pushed out actually have been left for dust, and are scrapped 3 weeks later and a new pop single is released.
If she released a Risky single and it was actually successful, MAYBE you'd have a point?
