It's extremely rare for music to contain anything below 30Hz. Even below 40Hz is rare. The only place you're likely to find such low frequencies is sound effects in movie soundtracks.
I should have said 'if the frequency goes sufficiently low'.
Unless you are into Bassnectar and the like... ;)
Interestingly, a lot of "bass heavy" music focuses on frequencies around 50Hz, not the really deep sub-bass. This makes sense when you consider human hearing. Those higher frequencies sound much louder to us, and they're still low enough to get the tactile feeling.
