Waka-Get this money (20hz)

[Sozzzz]

I don't usually listen to this type of music but I was suprised when I first played this off my phone not knowing about the low so I ran it through Audacity. Mostly 40hz but drops to 20hz a few times throughout the song at the end of the verses. http://www.hotnewhiphop.com/waka-flocka-get-this-money-song.706080.html
