The melody of Best Song Ever by One Direction runs 441 notes across 50 bars, 3:20 long in D 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.
