Confused about xesam:asText

[Alex Merry]

Xesam has been unmaintained for a while now (you could probably say the 
same for MPRIS, though, for all that mirsal and i are still monitoring 
the list!). It's one of my regrets about MPRIS that we picked a metadata 
format that didn't last very long.

That said, xesam was originally developed for the desktop search use 
case, so the metadata should generally be thought of as applying to 
files. That means it should contain the full lyrics. I don't think even 
xesam specifies the format beyond that - it's a general field for the 
"text version" of the file, whatever that means. I would generally 
assume it would contain a "human readable" version of the lyrics (in a 
similar format to what you might find on most lyrics websites).

If you want to provide lyrics in a format that allows syncing with the 
song text, it's probably worth using a different (custom) metadata key 
that you define to be in a specific format.
