I'm using Amarok 2.3 which has the kick-ass feature of automatically downloading lyrics for songs I'm currently hearing. Problem is, I want to download lyrics for ALL my songs. I can put all my songs in a playlist and let it run forever or constantly press the next song button, but I'm sure there's a better way... Is there?

(Even "preview mode" in which each song in the playlist is played for 15 seconds will suffice, but I don't see such a thing in my version of Amarok).

This feature doesn't exist in Amarok by default, maybe there is a script? There is currently nothing in the wishlist either, you should submit it
