1. Confessions Tour - Mindblowing. She won't ever top this, I think.2. MDNA Tour - Another incredibly stunning entrance. This tour had amazing visuals. The production of the show helped to enjoy it despite the terrible setlist.3. Drowned World Tour - Her return to the stage opening with a deep song that perfectly captures her growth as a person and as an artist. Then it blends right into the IMPRESSIVE performance of Impressive Instant. 4. Re-Invention Tour - Although I'm not a big fan of the GH concept, the intro really was great. The Beast Within and Vogue truly worked well as opening. However, I do think she should have opened with American Life.5. Rebel Heart - A good intro. It went downhill from there. I think she really wasted all the money on one unnecessarily long intro video that killed the production of the rest of the show budget-wise.6. Blonde Ambition - A simple but stunning entrance. Probably the best from her early years.7. Girlie Show - Nice but not really memorable.8. Sticky and Sweet Tour - Awful. Following CT this tour and opening were truly embarassing. She should have opened with Heartbeat, not this hot mess of a song. Her obsession with it and the fact she truly believes it's appropriate and fair to torture her fans with a performance of this utter piece of trash of a song is starting to make her seem delusional. (Note: I used to love CS but three performances in a row of a song that und' even a single made me hate it.)9. Who's That Girl - A snooze. But it was her second tour, so it's okay...10. Virgin Tour - MEH. I think Material Girl would have been a better opening.
