It does not work on all, but it does work on a lot of songs I know the lyrics to.
Sometimes you gotta change the melody slightly though, but still.
here's some examples (it's my electric guitar since I was too lazy to tune my acoustic so it's a bit quiet, also my voice hurts like **** atm):

1 - Choking Victim - 500 Channels
2 - Days N Daze - Misanthropic Drunken Loner
3 - The Menzingers - Good Things
4 - Ramshackle Glory - Your Heart Is a Muscle the Size of Your Fist
5 - The Menzingers - In Remission
6 - The Menzingers - Burn After Writing
7 - The Wonder Years - Suburbia
8 - The Flatliners - What The Hell Happened To You? (Hidden Track)
9 - Choking Victim - F***ed Reality
10 - No Cash - Skate or Die
11 - Streetlight Manifesto - Somewhere In the Between

There must be something most of these songs have in common.
