I really like the album.
It flows so well and the retro sound is done well in pretty much all of the songs.
Just the last three songs drag a bit as they're all ballads in the same style.
Without those last three songs the album would be perfect for me and I can listen to it through!
My faves are Baby Don't Play, One Black Night and OPPA.
The most interesting is Back though. Reminds me of the Hip Hop style in the '90s. Similar to The Fresh Prince from Bel Air.

Ah, and did I mention that I love the retro style?
