"Personally, this song is about loving yourself," Mariah added. "You have to love yourself first… If you don't love yourself, and you're not in a good place with you, than how can you love or do anything else to the fullest?"
The lyrics in question include biting lines such as, "Why you mad/Talkin' 'bout you're mad/Could it be that you just lost the best you've ever had?" And, "Why you tryin' to play like you're so grown?/Everything you own boy you still owe."
"We could take [all my songs] and dissect them and say, 'Who did she write this for?' And, 'What was that about?' But really, there's no way to say who or what was written about," Mariah said. "I also collaborated with different people, so there's all different input and things that happen in the songwriting process. And that's the great thing about writing a song -- you can express yourself, and you can express a little bit of everybody's emotions."
"I've never done anything like this before, so it's exciting," she added. "Doing all the No. 1 singles, that's something that can attract not only my core fans, but people that just know the No. 1 songs. Some of these songs I've never done live before."
The album and the Vegas show aren't the only things Mariah is focusing on in her life. She's also making sure to spend time with her children, Monroe and Moroccan -- who she welcomed with Cannon in 2011.
"They're my life," she said of her kids. "They make me happy, and if none of these things were going on, they'd still be everything to me."
