'Rehab' did just fine, the single didn't need to justify anything and was simply released to close the GGGB era. Perhaps a 'Breakin Dishes' release would have fared better in the charts but tbh that song deserved an early release when the album was fresh so that's kind of a moot point. Having Umbrella, Take A Bow and Disturbia all go to No.1 off one album, despite the releases, is very impressive and I don't think we should be bothered by an 8th single charting at No.18 when Beyonce's 3rd single in 'Halo' can't seem to even crack Top 30.

beyonce's halo is top 20 but besides that i the isngle did fine and considering it was an 8th single it did brilliant,but i think rihanna needs to go away for at least a year or she will kill her career over exposure,good good gone bad reloaded remixes etc has a few sales left in yet but i think she should concentarte and delivering a brilliant follow up make sure she lines up a killer first single and release it about june 2010
