High Fidelity-worshipping, vinyl-clutching bachelors everywhere will root for and lament along with Dan (Mark Ruffalo at his shaggiest), a down-and-out record label exec who wishes the music biz could go back to the way things were a couple decades ago. Dan meets and eventually becomes a musical mentor and friend to Gretta (Keira Knightley), seemingly a bird with a broken wing, recently cheated on by her douchey rockstar boyfriend (no acting required from Adam Levine).
