Some of her songs suffer from heavy compression on the masterbus.
Especially audible on „Ocean Eyes“, which is otherwise a great song, but the ducking is quite audible and doesn‘t suit the song.
But the mix is always very creative! The WHEN WE ALL FALL ASLEEP album makes copious use of LFO amplitude modulation , which I really like.
Just try it out!
If you have to turn the volume to 100% and it‘s still not loud enough, then you need an amplifier with more power.
