It would be cool if I could choose one of my own entries that I'm proud of and set it to be my "Featured Entry," so that when others view my profile, it is listed on the page with its own little Listen button, etc. And then I could switch it up once in a while when I feel like it.

Yes, that would be a very useful feature.

maybe we can have a set of featured entries

you can pick your top 5 personal fav botb entries and set them to the top

Hmm... I'd prefer having one entry at a time for "featured", but if you have multiple songsss you like, you could put them in a playlist and it could be randomly selected for every page refresh or whatever.

That'd probably be a lot more trouble than its worth, though.

Sounds like something that would cost b00ns!
I do like the idea of multiple featured tracks though. Maybe you can put more on your profile depending on your level? Since the higher level you are, the more likely you will have works you'd consider "featurable".
0-8 none, 9-16 one, 17-24 two, 25-27 three, 28+ four
Note: these are arbitrary ranges just to show what a balanced range that actual thought went into might look like.

having one featured track on a profile would be cool. wouldn't require too much work to do either i hope. 5 ain't necessary - it's botb not soundcloud

I suggest this feature be implemented as an item: the Vanity Helmet.

It will be second cousin to the Humility Helmet that allows you to remove your accidental self-favorites.

i'm going to feature an html entry
