Songkick provides concert dates to Spotify and that's where I found out about an artist I wanted to see playing in my city. I clicked the link, got to the Songkick website showing the artist I wanted to see and the date and bought the tickets. It's only several days later when checking the official website of the festival that I saw that the artist I wanted to see was actually playing 3 days later. Although the tickets I bought were valid they were for completely different artists. I ended going there and enjoyed it but I'll avoid using Songkick in the future.
