The melody of I Lived by OneRepublic runs 393 notes across 85 bars, 3:29 long in A at 115 beats per minute. The tab sits almost entirely in the first two frets, one note at a time — no chords to barre and no strumming pattern to keep up with. A piano backing track plays the chords and bass underneath, so the line you are learning sounds like the record even at half speed.
Prefer to strum and sing it instead? I Lived chords and lyrics.
