REMEMBER: This is based on my opinion.  Doesn't mean I am right or wrong.

1. Holler

Has a very solid and dramatic intro. I didn't know if I liked the beginning at first; however, it really gives the album a "hey TTS is back!" vibe to it. The chorus is marvelous, very catchy indeed, and makes me want to scream HALA! The verses are pretty okay. I would have liked to see a better build up between the verses and the chorus. The sound from the verse to the chorus was a bit too abrupt for me. The vocals were very refreshing to hear, listening to the first time; however, sometimes the vocals were a bit over the place. The rapping was very surprising to me, in fact, I definitely did not expect it. Overall, the rapping good, not too long, not cringe worthy... pretty solid. Finally, Tiffany's y and husky ending rift pulled the song in together.

OVERALL - 4/5 - Can't wait to see the MV!

2. Adrenaline

Oh my goodness, I am definitely putting this song on my running list, it's absolutely perfect! The drum beats are amazing, the build up from the verse to the chorus is excellent, and the voice synthesizing is absolutely impeccable. The chorus isn't too much, but isn't to little and there is a great balance between the vocals and the instruments. Each girl seemed to have an equal singing time and they all killed it vocally. This might be one of my favorite SNSD songs ever! 

OVERALL - 5/5 - Outstanding!

3. Whisper

The song is very, very smooth. I love the R&B feel of the song, making it very exciting and fresh. I haven't heard a song like this from SM in a long time. The bridge is pretty decent, yet I love how they're almost whispering as they're singing towards the end; definitely precedes the title of the song. Very much a baby making song (lol). However, unfortunately, the song does get a little boring if you are listening to it repetitively. After reading the romanization, this song is definitely sensual, hell it has a sensual feeling to it once you listen to it. 

OVERALL - 4/5 - Fresh, new, and exciting

4. Stay

All I can say is - WOW! This song has an amazing disco feel to it. I absolutely love it! The chorus is exciting, catchy, uplifting... I want to go outside and pick sunflowers while listening to this song (lol). Normally, I am not a fan of GG rapping; however, this song was perfect for a rap. Others may differ from my opinion with the rapping, but I really liked the cuteness sound of it. The bridge then slows down perfectly, and the whispering that's going on while Tiffany singing makes it even more amazing. I like it very much! 

OVERALL - 5/5 - No complaints here; in fact, this song should be in an anime.

5. Only U

A very predictable love song: cheesy, corny, sentimental... yet, I'm a er for these types of ballads. I can't complain. Seohyun did an amazing job writing this song! I am thoroughly impressed with her use of English. I love the cute, pretty sound of the piano as it's going from the verse to the chorus... lovely indeed. However, as the chorus goes into the bridge, the song seems to get a little repetitive. After listening to it about 5 times through, it gets a tad boring.
OVERALL - 3.5/5 - I really, really, liked it! Once again, the song gets a bit repetitive after a while; but if you're a er for ballads like I am, then you'll never get tired of listening to it.

6. Eyes

I am being a 100% honest, I didn't really like the song at first. It was very hard for me to judge at the beginning, but as I kept listening, I started to grow fond of the uniqueness and quirkiness of the song. Has a very f(x) sound to it and I can't complain that SM decided to take a chance with this song. I really love the beat of the verses, and the vocals as well. I also like how they spell E-Y-E-S. It makes me want to mouth the words every time I listen to it. What's very disappointing to me though, that it is WAY too short. SM shouldn't have any kind of excuse to put out a song that's under 3 minutes. I think I would have liked the song better the first time I listened to it, had it been longer.
OVERALL - 3/5 - I'm growing fond of this song, but it may take some time. However, I commend SM for trying something a bit new. Wish they could have made it longer.

For me, this album was absolutely outstanding. They had a great mix of catchy beats, to slow ballads and TaeTiSeo's vocals were incredible as always. I cannot wait to hear them live on Mnet Countdown tomorrow.  What makes me very happy is that SM decided to take a few chances with some of these songs, rather than playing it safe the whole time through. Also, I cannot be more impressed how the girls matured from Twinkle to Holler. Truly, I am satisfied.  This album is DEFINITELY worth buying.

OVERALL FOR THE ALBUM- 4/5
