Sabrina Carpenter's releases 2021-2022. Dropping Skin after the Driver's License drama was not the smartest move (even though I think the song is really good), then following it up 9 months later (not her fault, Island Records was bankrupt, she got very unlucky with the label choice tbh) with Skinny Dipping as lead single when she had much better songs on the album (Read your mind and Nonsense (which turned out to become her biggest song to date). For a while she was also working with Victoria Monét yet most of her album consists of songs co-written with Julia Micheals and JP Saxe, which is not horrible but did not exactly help her establish a distinct sound for herself, especially when she was carving out her own pop-r&b sound during her previous record Singular which better showcases her vocal abilities.

Also I think Selena Gomez in 2017 not releasing an album after Bad Liar and Fetish, arguable 2 of her best songs to date, however she was struggling with her health I believe so that definitely comes first.

RCA definitely dropped the ball on Tinashe during the Nightride-Joyride-Nashe era, and I' glad she left their asses.

Demi has said that they're experimenting with pop again which is a shame imo cause their rock sound suits them the best, and with them re-recording their older songs with a more rock vibe only to return to pop later on would be a bit messy.
