Seven Second Syndrome
Seven Second Syndrome is when you change radio stations and they are playing the last seven seconds of an awesome song that you haven't heard in years, immediately followed by an awful song that you despise.
When I flipped to the 80's station, I caught the last seven seconds of a Replacements song I haven't heard since college, then they launched into an extended remix of the sublimely-awful "The Final Countdown" by Europe. Damn Seven Second Syndrome again!
