Like Maura, I've been hearing "Let It Rock" on Z100 some; I think it's making the nightly request countdown now. (I like it, although I still say Weezy's rap is the weakest part of the song.) I don't think it'll ever be considered a credible rock or rap song, which makes for a promotional challenge for the whole Rudolf project -- they've gotta swing for the bleachers, ie big Top 40 stations, out of the box; they can't launch it at a genre format and then cross it over. Give them props, it appears to be working.

@Poubelle: You're exactly right about the Dec-Nov chart year making "Irreplaceable" the big winner, although I'm not sure a Jan-Dec tally *wouldn't* have made B. No. 1 anyway -- that song had massive chart points in '07 alone, including a week of huge post-Christmas sales. In spirit, I totally agree with you that "Umbrella" shouldve been tops for the year. Anyway, as long as Billboard continues to be a printed magazine with production deadlines the Dec-Nov year will persist, especially for the Hot 100; unlike album sales, for which raw Soundscan data provides a different result, no one can challenge Billboard on the H100 formula.
