Juxtaposed music on the radio
 

I'm curious, what are the odds of hearing the same artist four times in a row (meaning no commercial breaks, news/weather reports, or other songs in between, or anything else beyond a stinger), switching stations after each song? Or what are the odds of hearing the same song on four different stations at once? Well, I had both today. The letters in parentheses represent the callsign of the station.

Lady Gaga - Just Dance (KLUC)
Lady Gaga - Telephone (KLUC)
Lady Gaga - The Edge Of Glory (KQOL)
Lady Gaga - Poker Face (KMXB)
...all in a row with no gaps.

Taylor Swift - We Are Never Ever Getting Back Together (KLUC, KWNR, KMXB, KFRH)
...playing on four stations at once.

I remember once that "Wide Awake" by Taylor Swift was playing on one station (WPXY) and then another (can't remember for crap) afterwards. Two in a row is the closest I've gotten, but if anything it was the exact same song.

I don't know what station it was, since I was in my mom's old car at the time, but I heard Rihanna's "Birthday Cake" about 3 times on different stations. My mom doesn't like that song, and so she switched, and found it popping up everywhere.

My local stations are categorized mostly by era (Classic, 80's & 90's, Modern, etc.) So I don't have that problem very often. The only times I've heard repeating songs are during the holidays, where all you hear is Sinatra singing Christmas carols.

Oh man, don't even get me started on stations around Christmastime. Hearing a certain boring Christmas song (whose name I have forgotten) ten times, with five different versions, in the same day can certainly get annoying.
