The Superglued iPhone app is definitely the best thing you can do if you have an iPhone and will be at CMJ. Not only can you see the whole CMJ lineup, but you can get live updates of set times, set lists and more, find upcoming shows from artists and, one of the funnest features, you can tweet with other people at the same show.
If you don’t have an iPhone, check out Superglued.com for the whole CMJ lineup. If you do, download the app now. Seriously, you won’t regret it.
