OMG!!! Have NOT listened to BEGIN AGAIN for so long! Should have listened to it last night, it cures the pain caused by listening to my favorite CLEAN, even more efficient than TIM MCGRAW
Edit: Thanks BowDown2

and Ed Sheeran
Edit2: I don't know why, I could repeatedly listen to RONAN (and cry) for 2 weeks, but can not do the same to CLEAN which is definitely a better song than RONAN which I also love. I don't know why.
Edit3: A happy song (at least not sad song) after CLEAN at 1989 world tour is a MUST, according to my feeling today, BEGIN AGAIN is a good choice, but I doubt it.
Edit4: CLEAN first, then BEGIN AGAIN after, it makes sense though.
