Looking for more sublime chill songs like that...something not by Phoebe Ryan/Owl City/Lights and NOT Closer would be cool too

Ellie Goulding - Anything Could Happen?

That's the vibe I got from the song you posted except it's not electronic

Don't really sound alike but these bring me into a "chill-mood":
Say It (ft Tove Lo) - Flume
Hell No's and Headphones - Hailee Steinfeld
Breathe In. Breathe Out. - Hilary Duff
Back to Me - Daya

Hmm lemme give Hailee + Daya a listen, am familiar with Hil + Flume + Ellie, good choices

I recommend both EP's if you haven't heard them (Haiz and Daya)
And I forgot to mention Britney's Just Luv Me
