Here, without further ado, are some of the worst marketing moves made by bands this year:

Irrespective of who funded what, the cover of Weezer's album, Hurley, is still atrocious.
Weezer's Hurley. As in Clothing. Not as in Lost. Or Maybe As In Lost. Maybe.
As anybody who reads this site knows, we have nothing against corporate sponsorship and partnership. Like it or not, that's what's going to drive most large-scale, ambitious creative undertakings for the foreseeable future. But our regulars also know that these kinds of things have to be handled carefully, and after Weezer pulled a bait-and-switch on their fansputting Jorge Garcia, who played Hurley on Lost, on the cover, then announcing that their album had largely been funded by Hurley, a skate and surf clothing company owned by Nikea lot of their fans got fairly pissed off. A few days later, the band back-pedaled (and deleted that, too), video of guitarist Brian Bell saying that the album was paid for by the clothing company was pulled off YouTube, and people went back to complaining about how the band hasn't made a good record since Pinkerton.
Train's Publishers Really, Really, Really Over-Licensing Hey Soul Sister"
If a song becomes so ubiquitous that people get sick of hearing it, then somebody at a label is doing a great job. But if it gets to the point that somebody creates a website complaining about how many syncs that song has gotten, then maybe that label/publisher has gone too far. Train's Hey Soul Sister," a Grey's Anatomy-ready piece of MOR rock/pop, actually did drive Brad Meyers and Keith Stoeckeler to create Stop Advertising From Pulling a Train," and the site's raison d'etre resonated with the people. Everybody from Fuse to CNN picked up on it, and at one point the site got so much attention that it crashed.
Imperial Stars Blocking the Freeway...for Charity.
Generally speaking, a little scandal never hurt a young band. But you can't try to wrap said scandal in altruism, because that will make people go from annoyed to angry. Specifically, if you're going to do something as stupid as blocking the freeway during rush hour and then blasting your new single out of speakers, don't pretend you did it for a good cause. Not only will people ignore the cause, but they will come to hate you. Imperial Stars, the electro rap group who thought the above stunt would be a good idea, claimed after they'd gotten arrested that they would be donating proceeds of the song's sale to a children's charity. Amazingly, nobody changed their minds about the song, the group, or what they'd done.
Roger Waters' Marketing Team Defaces Elliott Smith Memorial in Los Angeles
Defacing public property in the name of promotion has become pretty commonplace, but defacing community memorials is usually a no-no. Yet that's what the marketing agency that Roger Waters hired to promote a summer tour did, when they covered a fan-made Elliott Smith mural with posters that were supposed to be part of a viral marketing campaign. Waters apologized for the move, calling it a mistake, but the damage was done. And while it's hard to blame Waters, who admitted that he'd never even heard of Smith, for what happened here, you'd think that he'd be able to hire marketers that are savvy enough to know where not to put their posters.
