They don't charge to look at stuff, but yes, it's a paid service to have them look up metadata for and keep track of everything sent to them by a station's automation system (or manually entered by masochistic operators, I suppose.) The results rely on the iTunes database, so artists who aren't in the iTunes catalog (like the Beatles until somewhat recently) only show up as exactly what was sent by automation (without extra metadata like album art and song previews,) and it also relies on a pretty strict match, so leaving off the parenthetical subtitle of a song or using a slash when iTunes used a dash will also fail to resolve to the correct record.
Actually going to "
www.tunegenie.com" doesn't allow you to learn very much about them, though, unfortunately; they seem to put a lot more effort into their product than into selling it with their website. The "explore affiliates" link on that page would probably give you some pretty good examples, if it actually worked, instead of all the links pointing back to
www.tunegenie.com.
You can try entering one of ours: wxrx.tunegenie.com
for an example of what it looks like when applied to a particular station, though users only end up at that view of the site after clicking on an item in the embedded "interactive playlist" on the station website (
www.wxrx.com in this case)
