During Terminator Salvation, John uses loud music to attract a terminator, and the song just happens to be "You Could Be Mine" by Guns N' Roses. For a large portion of the audience it's just a loud rock song, but it was also a fantastic easter egg to the fans who recognise it from Terminator 2.
I would have been overjoyed for something like that in ROTF. Say Soundwave is scanning across radio transmissions and among other music and voices there's a snippet of The Touch or Dare. That sort of easter egg that would make Transfans very happy.
