Headliner.fm is a service enabling bands to send messages to other (similar) bands’ fan base on MySpace, Facebook and Twitter. You need “band bucks” to send promotion messages to other bands and you get band bucks when you accept posting other bands’ messages. The idea is good, the user interface is slick and easy to use, but currently the selection of punk and poppunk bands is quite limited and since we’d only post messages from bands that we like, we can only hope that more good bands will join soon. So, if your band is interested, sign up here.
