I'm glad to see that someone finally built a Songkick widget. It does what it needs to effectively but does have room to grow into an amazing WordPress integration for Songkick. For the time being it does what I need, but I'm sure there could be more features added for artists to integrate it as their tour listings.
The only down-side I had was needing a new API key. It took a couple of days for Songkick to get back to me, which means the plugin isn't as plug and play as one would hope.
