Linda Perry wrote a series of hits in the early part of the 2000s, like Christina Aguilera's "Beautiful." Now, Perry's releasing her own album called "Let It Die Here." A MARTÍNEZ, HOST: In the 1990s, Linda Perry's band 4 Non Blondes had a huge hit with "What's Up?" (SOUNDBITE OF SONG, "WHAT'S UP?") 4 NON BLONDES: (Singing) And so I wake in the morning and I step outside, and I take a deep breath and I get real high. And I scream from the top of my lungs, what's going on? MARTÍNEZ: This song keeps finding new life, whether screamed from the stage at countless karaoke nights or even in mashups on TikTok. LINDA PERRY: It's one of those songs that there's always somebody screwing something up in the world. MARTÍNEZ: (Laughter). PERRY: And nowadays, it's amplified because of social media. But all the stuff we're going through we've gone through before. We just didn't know it. (SOUNDBITE OF SONG, "WHAT'S UP?") 4 NON BLONDES: (Singing) I said, hey. MARTÍNEZ: That is Linda Perry.…
