Have A Nice Day or Runaway for me. Both very good tracks that set the tune for the rest of the record.

Hey God has the honor to be the track that is by far the best on the album - for the first couple of spins, I didn't like anything else on These Days all that much. Especially the title track has grown on me, but IMO, Hey God is by FAR the best choice to open the album with. The same also goes to It's My Life, but there's other stuff on Crush that I also instantly liked.
