Show HN: Said.fm now with Semantic-ish Search

I'm a big said.fm user, and this is a very welcome addition. A small suggestion: when I go to a search page, for example:

http://said.fm/in/#/search/for/super

And select to see some results, it's not obvious what the icons do next to the results, for example the "infinity" icon. Perhaps add a hint, or tool-tip?
