I'm a big fan of Songkick, myself. I used to subscribe to a number of newsletters to try and find the gigs I wanted to go to. Now I get an e-mail from Songkick whenever an artist that I listen to is in town, and I certainly do use their links to go and buy tickets. It's been really useful for me. I don't think the value is just in the listing of the gigs, but how they've combined it with tools to learn who you listen to (aka track), and the social media connections (capturing tweets while you're at gigs, etc.). So while Last.fm has a more valuable dataset, Songkick as a whole has just as compelling a value to me as a concert-goer.
