Love to see this! As a classical music fan, I'm frustrated by how difficult it is to find good quality music online.
Here's a couple of ideas how to improve the tool:
* Links to Spotify, Deezer, et al. would be great (I particularly care about Deezer, because they offer(ed) the most comprehensive selection of classical music).
* I'm missing interprets. Search for "Karajan" yields nothing, yet Karajan is a super important figure in classical music. The same for the orchestras, string quartets, etc.
* Some people care about record labels, too. For example, I'd like to search specifically for DG, Decca and similar.
* I understand that the world of classical music is enormous and you'll never get all music. Improving the library will be an ongoing challenge. For example, there is Dvorak's Piano Quintet no. 2, but no. 1 is not present.
* I'm not sure I understand the UI. What belongs to the purple are at the top and what belongs to the white area below?
I might come up with more ideas later.
Hope this does not sound derisive, my points are just suggestions about how to take the tool further. It's fantastic that someone is working on this! Fingers crossed and keep up the great job!
