Madonna performed many songs from Ray Of Light on the Drowned World Tour, but there were still many missing, and after that tour she has only sung 3 of the album's singles. Which songs should she perform on a future tour? She called Ray Of Light her favorite album and moment in her career, so I'm sure that at some point she'll perform a few album tracks, as she also mentioned that she likes the idea of doing a tour with the fan favorites, B-sides and album tracks. The songs that haven't appeared on a tour are:

Swim
Skin
Nothing Really Matters
Shanti/Ashtangi
The Power Of Good-Bye
To Have And Not To Hold
Little Star

Some of these songs may have been performed at promo appearances, talk shows, award shows, etc. but they have yet to appear on a tour. Which ones would you like to see in a concert? Discuss, poll coming in a minute.

Nothing Really Matters is Madonna's best song, so that one.

Nothing Really Matter.
Swim.
The Power Of Good-Bye.

Nothing Really Matters

To Have And Not To Hold, the song is masterpiece!!!
