Personally, I like a lot of everyone. if you're putting out music i've probably heard it and/or like it lol. but some that I listen to consistently would be: Sabrina Carpenter, Ava Max, Kim Petras, and Ariana Grande if she still counts as pop.
as for favorite albums, I have quite a few but ill keep it to a minimum here, and share my favorite song from each one so you can get a taste of the albums without listening to the full thing. A few that I personally love and would recommend are: Diamonds and Dancefloors by Ava Max (favorite song: turn off the light), Problematique by Kim Petras (favorite song: Confession), and of course Short n' Sweet by Sabrina Carpenter (favorite song: Juno).
