My favorite One Direction song is Moments, off of their Up All Night album. It's a very passionate song. Their new songs seriously challenge Moments, but everytime I listen to it I'm reminded why it's my favorite. Each boy gets a solo that fits them well. Their voices are heavenly and the guitar is simply beautiful. The lyrics are so meaningful and it's written by one of my other favorite artists, Ed Sheeran. I think it's one of the best songs they sing live, they're phenomenal!! I hope to play it at my wedding one day.
