Help Plox

Hey, so I started listening to the Gorillaz song “Every Planet We Reach is Dead,” and I got the idea for a playlist full of chill music. I went through my Gorillaz music today, and I picked out a few songs. I was wondering if any of you musically inclined people knew where I could get more songs.
Heres what I have so far:

Every planet we reach is dead
Ghost Train
68 State

Anything like those would be good. I might add some Beatles stuff, so don’t list those.
