Nice service to get an initial overview. I am a regular festival-goer, but I prefer to go to more "underground"-ish festival (for the lack of a better word). Those festivals don't necessarily want to be easily discoverable (i.e. the Fusion festival in Germany goes great lengths to suppress the hype around it).
For me the discoverability problem is another one: In recent years, I am listening to so many new bands and musicians, that I am totally loosing track of their names. It occurred to me more than one time, that someone was talking about a band, whose name I thought I never heard before, to later find out that they did a song or album, that I actually listened a lot. This also goes for festivals: I walk around at a festival and hear a familiar song playing somewhere and realize, that there is a band playing that I enjoy a lot, but whose name I didn't remember at all. I know other people have this problem too and I assume this is a by-product of the UX of streaming music (when you have to put a CD or vinyl on every time you want to listen to a band, ofc you learn the names much faster).
So what I actually need is a service, where I can paste a link to a festival website, which the service scrapes and does entity recognition on. Then the resulting list of bands should be matched against my Spotify history and tell me the matches (either because I actually listened to the bands, or by some means of collaborative filtering). I am thinking about doing this in script form for this years Fusion festival, but would also like to know, if more people are interested in a service like this.
