Line breaks in playlist description

[toftat]

I'm spit balling an idea for an "aggregator" of sorts. The idea being that changing playlists can be automatically aggregated on a daily/weekly basis (think about a playlist with all of your previous "Release Radar" in it)

How I am thinking of doing this is having come metadata in the target playlist description that would allow the aggregator to find the source playlist. But mashing it all onto one line makes the description unreadable.it would be nice if it could be made to look like this 

Long, human readable description
that can span multiple lines

source:<playlist ID/URL>

as it stands it looks like

Long, human readable description that may get wrapped over multiple lines source:<playlist ID/URL>

which does not lend itself to human consumption, and god forbid, the work source appears in the human section.
