Review by Eric R. Wirsing at AllKPop.com. (Lightly edited.)
This is a really top-notch album. Well-packaged and the ballad-to-banger ratio is exactly right. There was a lot to love about this one, and I was jamming along to nearly every tune. Catchy, danceable, and just right for spring. Wannables are gonna want to snatch this one up. I promise U it's that good.
"Gold" is what they chose to kick off the album with. It's not a bad choice at all, but somehow it felt like a finisher, with those epic held notes in the chorus. But there was enough going on here to set the tone for the rest of the EP. Do I like it? You betcha.
Short for "I Promise You," "I.P.U." starts out quietly, but quickly builds into explosive notes in the chorus and becomes a pretty good pounding club-banger. It's their special theme track, released ahead of the mini-album. I like how this developed plenty of energy, and the chorus is bold and loud. A superb bop.
If I liked "I.P.U.," I loved "Boomerang." Loud, full of attitude, and sometimes annoying, this excellent track has everything going for it, as far as I'm concerned. After I heard "I.P.U." in early March, I wondered why they chose "Boomerang" to promote with. Now I know.
4. We Are
"We Are" continues the high energy theme, but this time in a more controlled manner. It's a good pop tune, with nice hooks and some staccato that I heart. I also like the synth washes during the bridge.
5. Day by Day
They slow it down a little with "Day By Day." This is more of an R&B tinged tune than the others, with a good chorus and a cool, smooth feel to it. I like it, particularly with the raps thrown in there for good measure.
6. I'll Remember
The first proper ballad on the album, "I'll Remember" is a really good one. I was a little worried at first, but it didn't degenerate into the ballad-by-the-numbers territory and retained its full of emotion throughout.
7. I.P.U. (Propose version)
As you might guess, the Propose version of "I.P.U." is another ballad. Have no fear, this is not just the vocal track run over a piano with a tempo change, this is entirely remixed, if not entirely re-sung. It sounds way different, with just enough there to remind you of the original.
