I don't know if I could solidly pick one over the other
+ has The A Team, Drunk, Small Bump, Lego House, Kiss Me, Give Me Love, Autumn Leaves, Little Bird, Sunburn
X has One, I'm A Mess, Sing, Don't, Photograph, Tenerife Sea, Afire Love, Even My Dad Does Sometimes, I See Fire (I'm very over Thinking Out Loud, overplay and concerts where I had to perform it killed it for me )
Divide has Castle On The Hill, Dive, Perfect, Galway Girl, Happier, What Do I Know, How Would You Feel, Supermarket Flowers, Barcelona (Shape Of You is dead to me by now)
All three albums are absolutely stacked and all are very precious to me. Ed is a brilliant lyricist and storyteller. Though I probably listen to X the most nowadays.
