First, Laura Veirs. Do you expect someone who looks as serious as Laura to hurt your headache? Never. Her best song is "Galaxies", but that can only be streamed from her music page, from the Year of Meteors album entry. Bedroom Eyes isn't bad either.
Like a lot of independent artists, Laura's site is a study in how to keep people from finding your music. Everything is in a crappy, tiny frame, and the best songs need to be streamed. I'm sure RIAA and her record company are very proud.
Imogen Heap's song Hide & Seek has had a lot of indy radio play and it won't bother your hangover either.
At the Hop is a mellow live cut from Devendra Banhart.
Finally, a little Belle and Sebastian: Another Sunny Day.
