What music piece if your favourite to play on Guitar?

[Shortie]

I don't play guitar even though I have tried, but for those that I know about who play, they always have a favourite piece they enjoy playing.

What music piece do you enjoy playing on guitar? What is the reason for this specific piece being your favourite?

I enjoyed playing these jazz songs from this book I bought a long time ago. They featured a melody played with a walking bass line. And all this is done by the guitar alone!
