I am trying to make a mix of songs with a vague sort of theme, but quite frankly I've been looking for about a month and this is all I've come up with... The songs are all sort of spacy in nature, some are pretty fuzzy, and for the most part they are all somewhat saccharine... I haven't yet started on order because I don't have enough songs, but here's what I have got so far:

Modest Mouse - Third Planet
Sonic Youth - Diamond Sea
The Flaming Lips - Do You Realize??
The Velvet Underground - Who Loves the Sun?
Neutral Milk Hotel - In the Aeroplane Over the Sea

I'm thinking of adding maybe some Beatles, some Jesus & Mary Chain, some My Bloody Valentine, and various other stuff, but really I can't think of anything. Suggestions would help immensely.
