Found this cool site to promote your band and stay in touch with your fans, pickRset:
In one word: Connection. This site allows bands to communicate with their fans and allow the fans to actually feel like they are part of the show and that their voice really matters. Let’s be honest, without the fans you don’t have a show, so why not try and give them what they want? That being said, if the band doesn’t play everything in the proposed set or, heck, doesn’t play anything from their requests (which is possible) it’s their choice. After all, it is their band.
