i think spotify creates genre names to fit them into their algorithms and that's how they've defined the general wave artists who are vaguely associated with pc music or have a similar listener base. you can see a visualization of it (and literally every other spotify genre) on this cool site. i personally like hyperpop wayyy more than any of the other terms that have been used to label the pc style
If you create an account you can see the page's editing history. It was just added by a user with the note "charlis single". From the editing history, you can see the creator's account; someone who has previously contributed to this bootleg Charli XCX album.

It's pretty comprehensive in terms of covering releases but some of the commentary is subjective (especially covering Bubblegum Bass) so Your Mileage May Vary.
PhotoScape X - it’s free for Mac and pc but I paid for the extras. It’s very handy, eyes are done using 2 sphere shapes with and outer glow effect and gradient fill. The rest is layered filters :) http://x.photoscape.org/
Bitwig Studio, I believe some guys that used to work on Ableton started it, I really really like it, the presets are pretty good, I usually use the FM synth which is decent
ableton and logic are probably the most common DAWs for modern electronic producers but i can't stress enough: you can use any DAW for anything! DAW choice is more about preferred workflow and doesn't really affect what kinds of music you can make or the quality of your music. grimes made visions in garageband.
anyway LMMS is free and Reaper has an unlimited free evaluation period. LMMS is a little quirky and limited (it's based around midi sequencing not audio recording, and can be weird with third party VSTs but comes with a lot of its own synths and effects) but i learnt how to produce with it and used it for like six years (and released two EPs) until i decided to switch to ableton
This is not an authentic file, it's a 24-bit/44.1kHz ALAC container of an upsampled [indeterminately 192-320 kbps in origin] MP3 file based on the spectrogram.
