This is interesting. I've had trouble timing several of the changes in Begin Again. I didn't think it had anything to do with the difficulty of the transition. If I just count the time aloud (one-and-two-and) everything is perfect, but if I'm trying to sing the lyrics, sometimes it seems like Lisa's chord change comes too soon. Anyway I've had Begin Again in my daily practice for two months and just yesterday I decided to shelve it and focus on the songs in various keys, some of which you'd think would be much harder than Begin Again, but they aren't.
