This feedback is coming from someone that wants to discover new / unknown bands in specific genres. I have a playlist of new / unknown bands I've discovered over the years, but searching with your tool didn't give back anything.
The playlist in case you want to use it for testing later: https://open.spotify.com/playlist/5DcbwcCkBde68RgsxO2Sn2
Ideas for improvement:
* autocomplete
* autocomplete with song, artist and album image
* allow for search by track & artist name
* match up one of my playlists with a playlist you have in your DB
