I created it 3 years ago to scratch a personal itch -- I was having trouble keeping up with all the bands I'm into. The website didn't become popular but it's still useful to me and a few thousands of other people so I decided to just make it free software.I would appreciate feedback on the website itself or on the code (I'm more of a backend guy).
