One aspect of radio DXing that appeals to some listeners is the search for "unofficial" stations - stations that operate without a licence in defiance of the rules that govern broadcasting in their home country. These are usually known as pirate radio stations. I don't normally go looking for these, but when I hear them I log them. In North America these stations often operate around 6925 kHz on shortwave.
On July 1, I caught a broadcast by one such station, Radio Ronin Shortwave, from 0210 to 0224 UTC. The signal was poor but I was able to copy it. They were playing oldies pop songs from the late 60s and 70s by bands like the Moody Blues, ELO, and the Eagles. There were also IDs and an email address to contact them at (email@example.com). The station appeared to go off the air at 0224. Shortly after that more pop music was audible, but I think it may have been a different station - Radio Ronin was in AM mode and the subsequent signal was SSB.
Another example of the amazing variety of signals you can find on the radio bands.
