I must be the biggest stan for FOB then because I can tell you ALL of their song titles when I hear them and just use the first couple words when referring to them. Not a problem and quite frankly albums full of 1 or 2 word titles look boring.

Unless it's a Fall Out Boy song, it doesn't really matter. FOB titles NEED to be long though. It's a law.

Unless it's a joke, it can't be too obscenely long, like Fall Out Boy's previous work...

"Our Lawyers Made Us Change the Name of This Song So We Wouldn't Get Sued"... like rly?

Or Cobra Starship... "Prostitution is the World's Oldest Profession (And I, Dear Madame, Am a Professional)"

When it's short, it just embodies the meaning of the song well!

I prefer short & medium length titles

It doesn't matter that much but 5 words tops is the best option, I mean "We Are Never Ever Getting Back Together"
