Favourite lyrics is a difficult one as its not something I really think about listening to music.
I'll go with a weird one, I love a bit of Sabaton for mixing metal and history. Why not go for the one they did about Scotland:
Rally all the clans
Englishmen advance
Blood of Bannockburn
Point of no return
Join the Scottish revolution
Freedom must be won by blood
Now we call for revolution
Play the pipes and cry out loud
