What's some good light hearted indie bands?

I don't mind if their mainstream or not, just some bands that are good
for summer!! Please don't suggest any Pop or 'punk-rock' it's not what
i'm looking for... Stuff like Noah and The whale or Stars, Maybe
Regina Spektor oh and Fionna Apple!!
I'll leave some links if you don't know who they are
