Miley Cyrus has been through a whole lot in the past year (such is life as the biggest tween sensation on the planet) and — as is seemingly required by Pop Star Law — most of that experience has ended up on her second album, Breakout. Though if you ask her about it, she prefers to describe the album thusly:

"It's for every teenager, or any woman in general," Cyrus told MTV News when she stopped by last week. "Most of my songs are for the girls who hate their current or ex-boyfriends."

Yes, meet Miley 2.0 (a.k.a. the All Grown-Up Edition), the girl who has survived roughly 1 million Internet rumors; about [article id="1574278"]500,000 tour dates[/article], [article id="1579938"]movie premieres[/article] and TV appearances; and exactly one very [article id="1590081"]public controversy over some racy Vanity Fair photographs[/article], and yet is — at the very heart of things — still just a 15-year-old girl.

While there are portions of Breakout (which hits stores Tuesday) that deal with the crush of celebrity and life in the spotlight, the majority of the record focuses on the kinds of things that concern the average 15-year-old: namely, hookups and heartbreak and everything in between.

"I hope [fans] can just take a way a lot from what I've learned ... like it says, it's a 'breakout' record. It kind of explains what I've been going through, so it's kind of a love song/ breakup record," Cyrus explained. "It's very kind of everywhere. You have to follow me on this one; you have to believe me that it's going to turn out great, that it does go together, because it's very wishy-washy, very back and forth."

Case in point: The album's first single, "7 Things," is a textbook breakup tune (the chorus features Cyrus listing off the seven things she hates about her ex) that also happens to be filled with remorse (the tune ends with a list of all the things Cyrus loved about the same ex). The lesson is that there are very few cut-and-dry situations in life, no matter how famous you are. It's one that Cyrus had to learn the hard way, and though she swears she's put the whole photogate thing behind her, she freely admits that it'll probably stay with her for as long as she remains firmly entrenched atop the tween-pop world.

"I think I've learned to just be a little more careful and really remember that for every action, there's a reaction," she said. "I have kept my heart guarded, for sure, because that is something you have to do for life in general, to make sure you don't get hurt.

"But also, I'm trying to not become callous, so that I can't feel," she continued. "Make sure your heart is there, but you know, not as open — be who you are, be able to say no. It's tough, but I think if you can do that, and do it gracefully, then it's awesome."

So, she's trying to walk the fine line between celebrity and normalcy, and you'll have to forgive her if she stumbles again in the future, just like you would any other 15-year-old on the planet. Of course, Cyrus is also very aware that she's not like most of her peers, which is why she's also set a new goal for herself.

"My main goal — and it's a big goal to take on — was that I want to change the world," she says. "And I think if everyone has that mind-set, to wake up every day and go, 'I want to change the world; I want to make a difference,' then that's what it's all about."
