Answer:

Cry Me A River

Not sure anyone ever got these two from the OP:

Q#1 Supertramp and The Beatles

Although Oh Darling was an acceptable alternative, I was going for Two of Us

Q#2 Bon Jovi and Pink and Linkin Park

Runaway

And Del Shannon

Yes, I was alluding to Del’s 1961 hit in my follow-up clue, which said both the artist and the title were referenced in songs by Tom Petty and Barenaked Ladies. So for extra credit, can anyone name those two songs?

The Barenaked Ladies one is “When You Dream”.

The Tom Petty one is “Running Down a Dream”
