One thing that I like about Happiness is that the composition is so different than what I'm used to from SNSD or f(x). It feels like there's so much in it because it's an upbeat song yet there's over a minute between each chorus and I don't mind it because there's no dead space, aside from that intro...
I also love how they all get significant parts in both verses. That's so unusual.
A ballad title track They are bold (Sometimes you gotta be bold to rock this world, boo ya - Queen Seulgi)
Look At Me sounds like IGCBOY's late sister
And U R Fired sounds so good
On an unrelated note, skip to 1:35 for Bom randomly serving serious vocals on Gotta Be You.
Like...I did not expect that.
She's actually improved this year, her pronunciation got a bit messier but the her flow is much better (which was one of her biggest problems imo). I really love her voice in the entire CRUSH album.
