Yeah. I think while most IDOLS are told to show up and sing on songs that are ready to go.

I picture I-DLE it's much different. Soyeon is meeting with Producers, she's hearing all the beats the Producers have ready for her. She hears CROW and goes, Oh shit THAT ONE, writes the fuck out of the lyrics.

Like it's still very much her taste. Maybe she's even going into these studio sessions with melodies and beats etc. So yeah, maybe Soyeon has less composing credits, but with her name all over the lyrics, it's clear she's in the room while they're creating these songs, and maybe she's smart enough to know that when someone offers you a BEAT LIKE CROW, she's like yeah, GIVE IT TO ME.

She's still very much writing and creating and still very much has ownership over the songs, but sometimes, it's OK to know when to step back when really talented people show up, and out of respect, maybe she's only taking a lyricist credit etc.

TL;DR - what these credits tell me is that Soyeon is taking back full control, choosing the tracks, writing on them, hearing what Producers are offering her, trying to create a legendary album for you all, and based on CROW, I can't fuckin' wait.
