A new(ish) destination for Idolator-reading R&B fans should be Andy Kellman’s R&B chart watch on the Allmusic blog, where he runs down the most recent debuts on the Billboard Hot R&B/Hip-Hop chart. Sometimes literally runs them down, as with with this double-zinged attack re. Usher’s “Dat Girl Right There”: “If Alicia Keys can score big with a three-drink-minimum karaoke bar Keyshia Cole impersonation, there’s no reason why this can’t go Top Ten.” Also a hearty WTF? @ OneRepublic making the R&B chart. Perhaps inevitable given “Apologize”‘s insane popularity, still sad thanks its to insane awfulness. [Chart Watch]
