It's a nice idea, but there seems to be a fatal flaw:

The first three entries that I tried all came back with terrible tracks.

In comparison, The Sixty One seems to have found a nice approach in limiting the tracks that you first encounter so that you're likely to have a good first impression and explore further. The stuff on their front-page tends to be really good stuff even if it often misses my genre sweet-spot.

You might consider something along those lines with curated tracks being the first encounter to make sure you get things off on the right foot.
