I will try my best to find the clips on YouTube but I imagine the example will be cut down a bit.
“You Give Love a Bad Name” by Bon Jovi – A depressed Dwight plays the song in the parking lot by the dumpster.
“Runaway Train” by Soul Asylum – A depressed Michael sings it on a stationary train.
“I Am Woman” by Christine Kittrell – Andy briefly quotes it (thanks “No Cuts”).
“Leaving on a Jet Plane” by John Denver – Michael sings it about Jim telling Pam he’s leaving.
“Take a Chance on Me” by Abba – Andy sings it with speaker phone friends (probably from “Here Comes Treble”) to Angela.
