Reminds me of when my daughter (at home) kept playing the Frozen soundtrack on my Spotify account, which I was listening to in the car via my phone... her choice would hijack mine and I was getting SO confused and annoyed... NO I DO NOT WANT TO BUILD A SNOWMAN!!!
Being a luddite, I don't normally bother with linking my phone up to the car when I set off. However, the other day I did and immediately the strains or Rossini's "Petite* Messe Solonelle" started up. I had downloaded an .mp3 of it when my choir was singing it a year or so ago, and it's still sitting there waiting to pounce.
*"petite" is a complete misnomer: it takes longer to perform than Beethoven's 9th symphony and the orchestra is considerably larger!
