Geez, there are zillions of these. One-word titles are where it's at. A 30-second look at my music library...
"Alive" Pearl Jam, Daft Punk
"Androgyny" Simple Minds, Garbage
"Angel" Jimi Hendrix, Massive Attack
"Arrival" Daft Punk, Zoe Keating
"Bad" Big Audio Dynamite, U2
"Birthday" The Beatles, The Sugarcubes
"Breathe" The Mission UK, U2
"Burn" The Cure, Nine Inch Nails
"Cascade" Afro Celt Sound System. Peter Murphy
"Changes" David Bowie, Yes
That's 10 and I'm not even through "c" yet.
For many of these, I'm sure there are more artists that go there. I mean, how many bands have a song called "Angel"? Gotta be at least 50...
For "Liar" besides what we have already there's also New Order, the Cranberries, and the Sex Pistols... and probably more.
So if you want to make it interesting, maybe only songs with at least two words in the title (and "the" doesn't count). Like...
"You Don't Know" Berlin, Curve
"4th of July" Soundgarden, U2
