“I’ll never lose us again,” Billlie sings as they come back stronger than ever with their fifth mini album, appendix: Of All We Have Lost. Shedding light on their exhausting “B-side,” the group pops in the “remembrance candy” to reminisce over the wonderful times they’ve spent together and they “jump on trampoline” to turn all their old worries into “dots.” The songs on their new album form the back pages of the vibrant read that is Billlie, and below, the group talks about the songs that accompanied them on their journey.

“remembrance candy” (Billlie)
MOON SUA: I feel like this song does a good job of conveying the message we were going for with the new album, and the lyrics IU wrote are just beautiful. You’ll be able to sense the happiness on our faces every time we perform it! The song’s even better if you listen to it along with watching the performance!

SUHYEON: Prepare to see a completely different side of Billlie you’ve never seen before! I hope you can feel the balance between the exciting music and the deep meaning of the lyrics!

HARAM: This song’s about calling forgotten feelings back to the surface. It’s a heartwarming song that will touch anyone as soon as they hear it. I really recommend it! It’s very reassuring.

TSUKI: “remembrance candy” is a very therapeutic song. It’ll make you feel like you’re going to have a good day when you listen to it. I hope you start your day right with “remembrance candy”!

SHEON: IU wrote the lyrics for this song, and it sounds as beautiful as candy coming out into your hands. I really hope you’ll check it out!

SIYOON: “remembrance candy!” The melody rolls along like candy, the lyrics help you remember something important you’ve forgotten, and the performance is cute and clever! Everything about this song’s sure to please.

HARUNA: This is a really important song for us, written by IU, who we absolutely love and look up to. And we hold microphones in our hands for the first time for the performance, so be sure to check it out!

“trampoline” (Billlie)
MOON SUA: This is a nu jazz song, a genre I like. You’ll get to see a different side of the group compared to “remembrance candy”! I think it perfectly captures the feeling of bouncing up and down on a trampoline. You should picture that while listening to make it more fun!

SUHYEON: This song started with talking about what can make you feel stronger when you’re already feeling tired and worn out. Give it a listen when you need a boost!

HARAM: This song contains a message of hope. It’ll make you feel better and set your heart soaring if you listen to it on a rough day.

TSUKI: Listen to this on your way home from work or when you go out for a walk at night and it might turn even your repetitive routine into a cherished memory.

SHEON: The rhythm of this song gets catchier the more you listen to it and the lyrics are full of hope. It’s so good that you’ll realize why we went with double lead singles this time. I’m sure you won’t regret listening to it!

SIYOON: This uplifting song will bring back childhood memories, just like “remembrance candy” does! Personally, I feel like it brings back that wonderful feeling of anticipation and that sense of hope from when you were a kid!

HARUNA: This song’s super catchy and is a perfect showcase for what makes each member of the group’s vocals special. I hope you like it, everybody.

“Bluerose” (Billlie)
MOON SUA: This is one of my favorite tracks off the album. It’s a city pop song that triggers the senses and feels like a dream—almost like a fairy tale. It’s especially meaningful to me because SIYOON and I helped write the rap! :-)

SUHYEON: We tried to bring another flavor to Billlie with this cool city pop song. It shows a different side of the group’s charm and vocals!

SIYOON: Seeing “Bluerose” under the moonlight, something imagined that may or may not be real, and an illusion that follows you—I started thinking maybe all of this could be pointing towards hope. I hope you will believe in and accomplish whatever you make for yourself.

“shame” (Billlie)
HARAM: This song is about the complex emotions we all experience. I think a lot of people will see themselves in this song and relate to it.

TSUKI: This song lets you put your thoughts and worries aside for a minute. I hope you pay special attention to the chorus!

SHEON: I really love this track. The way the lyrics unfold is so good and the melody’s really catchy, so I really hope you give it a listen!

HARUNA: The melody, lyrics, and the whole vibe of this song make it fantastic. I’m personally listening to it more than any other song off the album!

“Drowning” (WOODZ)
MOON SUA: I came across a video of him performing this song live, and he’s such a good singer … so talented … I usually need time to fall in love with a song and don’t like it right away, but I fell for this song instantly and watched his performance over and over! ❤️

“Raye” (John Splithoff)
SUHYEON: I really love the genre of this song. He’s got really standout vocals and the song’s so charming!

“Feel My Rhythm” (Red Velvet)
HARAM: Red Velvet has amazing vocals and harmonies, and this song gives good vibes even on a bad day. It makes you feel good the entire time you’re listening to it.

“Almost Love” (Sabrina Carpenter)
TSUKI: I found out about Sabrina Carpenter through this song. I’m recommending it because I used to listen to it all the time whenever I was going to the label or taking a break in the practice studio!

“camping everywhere” (george)
SHEON: This song is really therapeutic. The rhythmic beat is great and the lyrics are so unique and cute. It makes you feel like you’re taking a vacation.

“Warmhearted” (Choi Yu Ree)
SIYOON: Belllie’ve recommended this song, so I gave it a listen! It was really touching because it felt like it was something they wanted to say to me. I love how moving the lyrics are!

“NEMONEMO” (YENA)
HARUNA: I heard this song when I was promoting recently with YENA. It’s such a cute song and so memorable that I can’t stop listening to it!
