How do I add songs to an existing playlist?

[JoanofDark]

I have a playlist that I like and I'd like to add a couple of songs to it. How do I do that? I see that it's possible to delete songs, but is there anyway to just add a couple songs without having to create another playlist that is almost exactly the same as the first one?

ETA- Nevermind! I figured it out while creating a new playlist!
