Letra de It Don't Mean A Thing

What good is melody
What good is music
If it ain't something sweet
It ain't the melody
It ain't the music knows
There something else
That make's the true complete
It don't mean a thing, if it ain't got that swing
(doo-ah, doo-ah, doo-ah, doo-ah, doo-ah, doo-ah, doo-ah, doo-ah, doo-ah)
It don't mean a thing all you got to do is sing
(doo-ah, doo-ah, doo-ah, doo-ah, doo-ah, doo-ah, doo-ah, doo-ah, doo-ah)
