“Create a single playlist with all the songs - from the device memory + microSDHC card.”
Have you actually gotten this to work? I don’t use playlists on My Clip Sport, I did use the Go List on My Clip+ and Clip Zip before I started using Rockbox. On the Clip+ and Clip Zip whole albums (or even all the songs of an artist) can be added to the Go List in one step. The instructions for playlists on the Clip Sport is that the playlist needs to be in the folder that contains all the songs, which means that a playlist could be for songs on card memory or on internal memory, but not songs from both.
