Great initiative, but if it's sampling only the few seconds previews from the songs, then I doubt it will be useful. Also, a language filter is essential for both training the model and listing the results. I searched for a few Hindi language songs that I know of, and it listed only English, Chinese and Spanish songs as related ones - which is good to explore other music, but at times I'd just want to be in my native language zone and any other language would exercise my brain more than it'd relax it.
