I haven't been posting or even following Maachan's weekly karaoke segments lately. This one however, interested me because she covers one of my all-time favorite singers: aiko.
YoshiKara #57: Aiko Special Karaoke Livestream
2:57~ Koi no Superbowl (2011; peaked at #4 on Oricon)
14:54~ Bye Bye! (2021, album cut from Doushitatte Tsutaerarenai Kara)
26:06~ Soushisouai (2024; #9)

aiko's indie career started in 1997, the same year that Morning Musume began, and her first charting single was in 1998, same as Morning as well.
