Tilt contains six tracks. The title track, was described as a highly addictive pop dance song that blends a restrained R&B groove with a powerful electronic beat. The track explores the theme of mutual growth in a relationship, not as a contest of winners and losers, but as a journey toward building balance together. With its emotionally charged arrangement and thoughtful lyrics, it delivers a nuanced message about connection, harmony, and shared strength.

The second track, "What's Your Problem?", is a modern reinterpretation of the 1990s hip-hop R&B sound, blending nostalgic elements with a contemporary edge. Adding a bold layer of synergy, Julie of Kiss of Life joins as a rap feature, enhancing the track's dynamic energy and empowering message. The third track, "Irresistible", is an R&B pop dance song driven by rhythmic acoustic guitar and captivating vocals that create a subtly mysterious atmosphere. The lyrics narrate the process of falling under the spell of an alluring presence, only to reveal, in a playful twist at the end, that the object of fascination is oneself. The fourth track, "Girl Next Door", is a pop dance track that showcases powerful vocal performances set against an upbeat, rhythmic drum foundation.{{Cite web|script-title=ko:'컴백' 레드벨벳-아이린&슬기, 솔직 당당 애티튜드|trans-title='Comeback' Red Velvet-Irene & Seulgi, Honest and Confident Attitude|url=https://m.entertain.naver.com/home/article/609/0000988520|via=Naver|publisher=Newsen|language=ko|last=Hwang|first=Hye-jin|date=May 19, 2025|access-date=May 26, 2025|archive-date=May 26, 2025|archive-url=https://archive.today/20250526115922/https://m.entertain.naver.com/home/article/609/0000988520|url-status=live}}

The fifth track, "Trampoline", is an R&B pop dance song that stands out for its haunting and immersive atmosphere. The lyrics convey a deep yearning for someone to become the sole light that guides you through a dark night, shining endlessly with unwavering brightness. The sixth and final track, "Heaven", was described as an R&B pop dance track that blends a simple drum pattern with layered synths, keyboards, and distorted guitars to create a dreamy, groove-laden soundscape.

On April 14, they announced their first Asia tour, Balance, kicking off in Seoul on June 14.{{cite web|script-title=ko:레드벨벳 아이린&슬기, 6월 데뷔 첫 아시아 투어 개최|trans-title=Red Velvet's Irene & Seulgi will hold their first Asian tour in June|url=https://isplus.com/article/view/isp202504140063|website=Ilgan Sports|language=ko|last=Park|first=Se-yeon|date=April 14, 2025|access-date=April 14, 2025|archive-date=April 14, 2025|archive-url=https://archive.today/20250414121259/https://isplus.com/article/view/isp202504140063|url-status=live}}
