It would seem that no stage is too big for a certain degree of pettiness for our president-elect, as Donald Trump appeared to be using Thursday's (Jan. 19) inauguration welcome concert as a golden opportunity to troll The Rolling Stones.

Trump had previously used multiple songs by the rock legends, including "Brown Sugar" and "You Can't Always Get What You Want," to soundtrack his rallies, before walking out to their 1981 hit "Start Me Up" at a May victory speech in Indiana. That may have been the last straw for The Stones, who formally requested that Trump cease his use of their music, telling Billboard that they "have never given permission to the Trump campaign to use their songs."

However, Trump appeared little dissuaded at today's concert, playing a trio of the group's classics ("Let's Spend the Night Together," "You Can't Always Get What You Want" and "Heart of Stone") as his playlist for the proceedings. The deployment of the songs was conspicuous enough -- "Heart of Stone," one of the bitterest love songs ever released, soundtracked Trump's entrance alongside wife Melania -- that it was difficult to explain as anything but an extended nose-thumbing at the band for attempting to deny the president-elect use of their music.

Billboard has reached out to The Rolling Stones for comment.
