Similiar Songs in the Song Drill Down

What I’m envisioning is another circle button when you click on a song, that would lead to a list of songs similar to the selected song, from which you can add to queue. And if you can keep cascading down to similar songs from a similar song, that would be even better.

The songs could be the same as what would be populated from Start Radio, but would give us a way to control the “Radio” a little more than the Thumbs Up and Down in the Queue window.

Technically, you can already do what I’m asking for in other ways, but I think it would be nice.
