I don't think "Piñata Attack" was specifically written as a Halloween song, but between candy theme and Lucky Diaz' slinky surf guitar line, releasing a video for the song (from Lucky Diaz and the Family Jam Band's Adelante album) around Halloween seems... appropriate.
If it makes you feel any better, the fact that it's a lyric ("letra") video should give some substance to the empty candy calories, right?
