My God, where to even start...

Not as popular as HF, but, hundreds, if not thousands of users globally, 
daily.  Military, experimental, foreign broadcast, voice, music, data, 
Ham radio, GPS correction signals, time signals, aviation beacons, 
traffic information stations, radiofax, maritime, there's a lot of RTTY 
just below the AM broadcast band, I hear it when driving at night, the 
list goes on, and on...

Then, check out:

www.vlf.it  which appears to be down t the moment.

Some broadcast stations:

Sometimes I hear a station on 189 KHz, maybe the Italian station listed, 
but sometimes I think Iceland.

There's actually a lot there, it just seems nobody bothers to check.
