Best: Madonna, Mariah, and Katy.
Worst: Alicia Keys. She bored the living out of me, and there was a 6'5 man in front of me who blocked my view throughout the whole thing.
Best: 5H's Summer Reflection Tour & Ariana's Honeymoon tour definitely the best concert experiences i've had
Worst: idk maybe Warrior Tour...great show but we had horrible seats and couldn't see anything
Best: MDNE Tour
Worst: Zoe the arena was half empty, played many unknown songs which were pretty much the same, and the people next to me brought this smelly pasta
The Mrs. Carter Show was phenomenal it definitely wasn't bad
I've only ever been to the TPP tour twice.
I guess I could answer this properly next year since i'll be seeing Marina, Janet & Mariah.
Even though I love her and will spent a **** load on tickets, Mariah will prob be the worst since her voice isn't what it used to be.
