I myself go one step further: after i fetched correct lyrics i store it
in ~/.lyrics/artist-title.txt and when i want to show it again i first
try to open this text and only if that fails i try to fetch it from
somewhere else ..
I also only load lyrics if i really want to show it (in a
notification) - so i think it does not make much sense to put int in
vicious, also funny things will happen when the server replies really
slow ...
