I like the idea. Maybe you could leverage Songkick API to support more cities ? (I moved to Tel Aviv recently and it's really hard to spend the time to find out which concerts are worth going to)
Ben from Songkick here and we'd love to work with you on this. If you reach out to me I'd be happy to sort you out with API access. ben[at]songkick[dot]com
It's a shame you decline any apps with monetisation ideas. I think it would be better to offer a paid API service a la Google APIs than to have so many engineers reinvent the wheel. Oh well, I guess the music industry and logical business models never did go hand in hand :/
Yeah, just wanted to ask if you use an API to get events?
I've been working on something in a similar direction for Vienna. Tried to get SongKick API access, but they declined me. I also used BandsInTown on a project, but it's a bit limited. These days I'm just using Facebook Events, which is ok, but not perfect – can't get all the events in a particular city automatically. Managed to manually overcome this though.
But great work! Tried the app out and I really like it. Followed you on Twitter if you want to keep in touch. Would be nice to have some MusicEventsHackers group to discuss these topics :)
