In Part II of our special Year in Music New Music Report, Christian Hoard dissects Rolling Stone’s 100 Best Singles of 2008 list — led by Beyoncé’s “Single Ladies” — and reveals his personal picks for the category, which include tunes by the Knux and Ida Maria. Plus, a look at the Best & Worst Ideas in Rock, from selling your record at Wal-Mart and outsourcing your lead singer (a la Journey’s Arnel Pineda) to bragging about leaking Chinese Democracy and giving your kid a ludicrous name. And our holiday gift to you: a look back at one of our favorite RS videos of the year: MGMT’s hippie-dance lesson from backstage at Bonnaroo.
