Earworm of the Day: Por Una Cabeza

It usually takes two to tango, but only one to get an earworm.

This is probably the single most overplayed tune for tango in show biz today (on those dance shows, in the background on TV series, and in quite a few film), which is why it can worm its way into a person's subconscious. Sometimes the show is worth seeing, sometimes not so much (although Colin Firth almost rescued this one).

In the contest for a person's sanity, though, the song always wins anyway, at minimum by a head.
