I'm sure this has been done, but a basic search didn't turn up exactly what I was looking for, so I did it myself.
THE REALEST SUMMERJAMS was Ryan's epic summer jam list. Constructed and curated in a way only Ryan could pull off. Unfortunately, I have RDIO, not Spotify, and I'm not switching. So I used resp.in to bring it over. Here it is in all its glory:
First glance, it looks accurate. However, there are about 200 songs Ryan had on the list that are not playable on Spotify anymore (probably license issues). I'm going to go through them by hand and see if I can get some of them in on RDIO. If anyone notices any other errors, let me know, and I'll fix them up. Enjoy.
