Hi Ruru !! 👋
I have so many asakiku ones the most asakiku song I can think of is You Don't Listen to Rock by Aimyon ,,,, I love it so much it reminds me so much of Arthur .... I'd like to think of Arthur being a cause behind Kiku being an absolute j-rock fan
Probably also I Love... by Higedan, Kimi janakya Dame mitai by Masayoshi, Darling by Keina Suda ← This one is literally Arthur song no.1 imo... , Neko by Dish, 1/3 no Junjou no Kanjou by Siam Shade, Pujaanku by Masdo ... I wonder if its obvious what I usually listen to 👶

As for swi, I don't have that many but Rookie by Deco*27 is super Swi to me... !!

You can tell between asakiku and swi which one has a dedicated playlist LOL
