From the snippets: This Is How We Do, Walking On Air, International Smile, Legendary Lovers, Dark Horse, Birthday, Unconditionally and Roar are the best tracks (not in any particular order) that's 9/13 of the album. Not bad.
The singles should be:
1 Roar (

)
2 Unconditiknally (:jamming)
3 This Is How We Do

4 Legendary Lovers

5 International Smile
Perfect era.
Edit: Unconditionally grew on me really fast.
