“What ___ Done” (Linkin Park song)

I’VE

["This hit from Hybrid Theory starts with the lyrics \"In the end, it doesn’t even matter\" and features a contraction in its title."]

This clue references the 2003 Linkin Park song "What I’ve Done", where the missing words in the title fill the blank. The answer is "I’VE," the contraction of "I have," which completes the song’s name. It’s a straightforward fill-in-the-blank based on a well-known track from their Minutes to Midnight album.
