Radio station Whack-a-Mole

Disco(graphy) for the eyes. As the Angela Gunn USA Today blogpost that alerted me to this puts it, "This one shouldn't be nearly as addictive as I'm finding it -- yes.com, which lets you find out what's playing at thousands of radio stations around the country. You can see what's spun during the past 24 hours or check out a station's top 100 hits; there's also a song-ID option and the whole thing links into iTunes for your purchasing convenience. Honestly, though, it's the map on the front page that's got me mesmerized. All those songs playing here and there -- it's the radiocentric pleasure of a cross-country drive without the trouble and expense of getting behind the wheel. Click the link and stare along with me."
