It is relatively easy (currently) to take a playlist and back it up as a plain text file.
CTRL+A, CTRL+C from web or desktop puts a newline separated plain text list of songs on your clipboard.
Main risk is that the list is in the format of "https[:]//open[.]spotify[.]com/track/[song-id]", so Spotify may break the lookup of these IDs in the future.
