I made an app like this a long time ago called "Showhopping". Its intention was to get people out to more music events by helping them discover artists similar to the ones they liked. I really just earnestly felt like people weren't going to enough music events, and missing out on a great activity to engage in! I eventually ran out of steam on it when BandsInTown and others joined the scene, but it was great fun for a while, and I even ended up on lifehacker at some point. Good luck with your venture!
