I am really enjoying the free web service called SpotiOrg.com. With it you build an album view of albums that you search for and then save. It's albums only; not Playlists. When you play an album it automatically launches it in Spotify. Works well for me on Mac desktop, iPad, and iPhone. No, I'm not affiliated with SpotiOrg, just an enthusiastic user who would like to seem them thrive. There have been a few growing pain issues but their support is very responsive and the biggest bugs seem to be worked out.
