Olivia Hye of LOONA is the youngest member of the 12-member girlgroup, born in 2001, and being a trainee for only a reported single day before debuting in LOONA (or technically getting selected, LOONA did not 'debut' until after the individual promotions).

Olivia Hye got her chance to take the spotlight with her turn at the microphone, with the 2018 single 'Egoist' inside the 'Olivia Hye' album under LOONA's name. Yeah, it's kind of confusing but that's how LOONA's timeline worked, these individual member releases were not considered part of the official debut for the group.

Today I'll be listeing to Olivia's single 'Egoist' and dissecting the composition, her vocals, and most importantly what I like about the song.

0:00 - I already love how airy and roomy the composition is already, one-note piano keys echo and bounce around the air to give a pure and refreshing start to the song, as well as some mystery about what the song has to present.

0:10 - Olivia's vocals are also airy and tranquil especially since the already spacious instrumental is still continuing on. Olivia's vocals are also on point her low tone and whispery singing here. I also love the subtle kicks in the back to convey the rhythm of the song whilst the rest of the composition does their thing.

0:30 - The whole composition picks up here very suddenly, going from a mellow, calm, and dreamy vibe to an immediate uproar of heavy and punchy instrumentals, and the atmosphere is even more elevated by the rise in octave by Olivia, she is now singing in a regular tone and not in a whispery manner anymore.

0:39 - I love the gentle "oooooh" subvocal in the background to compliment Olivia's sharp and descending vocals to pitch the vibe of the song down.

0:51 - Olivia's vocals really convey how excellent they are here. The instrumentals pick up another notch as well as Olivia's tone. I love the ascension in the instrumental when Olivia also raises her tone just after the drop to the chorus.

0:56 - It's very faint, but there is a subvocal from Olivia a few octaves lower than the main vocal which is giving the main vocal sample body and elevating her vocals.

1:12 - This post-chorus bears a lot of resemblance to the intro and first chorus, it's very airy and roomy, especially since Olivia's vocals have kept that reverb and echo effect throughout the song so far.

1:34 - This part caught me off guard. Throughout the song so far, I got this dreamy and drowsy vibe given how spacious and airy the song is, but this electronic drop is something else. It's like the previously-subdued instrumentals are exploding and roaring out here.

1:51 - Jinsoul enters here with a rap which I found uncoventional but it works as a contrast to prevent the song from being too linear. I like this switchup with the dirty and rough vocals from Jinsoul combined with the bassy and punchy instrumentals.

2:11 - This section of the song comes back to the more upbeat and highkey composition which is a great transition from Jinsoul's part and also keeps the song energetic for the upcoming chorus.

2:32 - The rise and lows of Olivia's voice are truly the gripping parts of the chorus especially given the evident stings from the instrumental which follow Olivia's vocal tones.

2:52 - I like that the bridge comes back to the intro's simple and dreamy instrumental. What makes this part even more roomy and airy is Olivia's vocals have reverb and echo, as well as the faint subvocals that promote even more room and space.

3:17 - One last chorus to finish it off is fantastically done. The chorus has been transitioned from either a) a mellow and dreamy verse, b) energetic and exciting. Here we see a repeat of the dreamy and sleepy vibes from the first verse which is a nice callback to the song's atmosphere and keeps that mystertious and dreamy vibe that the song has retained throughout the song. It's so pleasurable.

This song is so pleasurable to listen to. The whole song throughout excluding Jinsoul's part is airy and echoey, which gives this expanded and atmospheric vibe which naturally makes the composition more spacious and sound so fresh and wwide. Olivia's youthful and soft vocals also help this vibe especially given her vocals throughout the song have a reverb and echo effect on them. That's not even mentioning the lower subvocals that even further give the composition room and body.

Jinsoul's rap broke up the composition surprisingly well, without her rap, the song in my opinion would've sounded linear, but the addition of Jinsoul's part keeps the song from being too boring and forgettable by inserting a changeup in tone and style.

Credit has to be given to Olivia, she is the youngest member of Olivia, born in 2001, and already has stellar vocal ability. Giving an idol that is under 19 a solo single, is a risky tactic, but it worked fantastic. Olivia's voice perfectly fit the instrumental tone, the verses had high tones to compliment Olivia's vocals, and when the chorus drops, the instrumental picks up a bit along with Olivia's voice. That is amazing composition design.

Overall, I absolutely love this single, the composition is what makes the song so great, the uniformity between the vocals and the instrumentals is amazing.
