Rdio to Google Play Music All Access

Hi everyone. I'm a recent convert to Android from iOS and I'm really interested in trying out Google Play Music All Access. I use Rdio now but I find its app really confusing and slow compared to GPMAA, which is very "Androidy" (in a good way) and responsive.

The problem is that I've made lots of playlists I rely on in Rdio and can't figure out a good way to port them over. (I saw someone hacked Portify to work with Rdio, but I haven't been able to get it to work myself.) Has anyone made the same switch? If so, do you have any tips or suggestions? I'm not sure I have the time to manually rebuild these playlists.
