More than just a coincidence, surely…
Something really amazing happened at church tonight. Our minister played a video featuring a track by Hillsong Music, called Let Your Kingdom Come.
When it first started, I thought to myself, “I know this song”. I knew I had the album, and I knew I had it in the car. So I checked it on my phone, and this is what I saw.
Note the symbol before the time against track number 7?
The point here being that not only did I have that exact track on my phone, but it had been the last track that I had played on my phone during the course of last week!

No. Not more than coincidence.
How many times have you heard a song played in church (or anywhere else for that matter) that does _not_ feature in your most recent playlist. Almost certainly very often. You don’t blog about those coincidences though do you? :p
You make a good point, but flawed due to one thing… I do not have anything remotely resembling “mainstream” on my phone. I would react (and have done so in the past) to any instances where a piece of music on my phone was played elsewhere when I hadn’t expected it to be. Even more so when the song in question was both unexpected and the most recently played track on my phone.
I respect the point you were trying to make though.
