Cusack & Gabriel pay tribute to their iconic 'Say Anything' sceneIt could be argued that the scene in Say Anything, when starry-eyed high school senior Lloyd Dobler attempts to woo back his ex-girlfriend Diane Court by boombox-blasting Peter Gabriel's "In Your Eyes" outside her suburban bedroom window, is one of the best uses of a pop song in cinematic history. And history was certainly made again this past Saturday night, when at Gabriel's Hollywood Bowl concert commemorating the 25th anniversary of his landmark album So, Mr. Lloyd Dobler himself, aka actor John Cusack, made a cameo on the Bowl stage.

Slowdive and Mojave 3 alum Neil Halstead is back with his third solo album of introspective folk music that leads the listener to become suspended in the moment. A fusion of 60s British folk with flourishes of American country, Halsteads music shies away from effects pedal-tapping soundscapes of Mojave 3 while still retaining the spirit of their music.

Halstead told Y! Music that when he first went solo, he found himself in some unfamiliar territory when people would approach him with a guitar and a wide-eyed request to play something. Having relied on electronic components for so long in Mojave 3, Halstead focused his solo efforts on being as lo-fi as possible. And it worked: The man hardly needs more than his voice, an acoustic guitar and a listener to be as affective and moving as a full orchestra.

Mary J. Blige stole the second night of the iHeartRadio Music Festival in Las Vegas, bringing the elusive Prince on stage as her surprise guest.

Four songs into her set, the Queen Of Hip-Hop Soul stopped her band from playing Chaka Khan's "Sweet Thing," a song she covered on her 1992 debut album What's The 411? "I got a real good friend in the building. He's one of the most amazing artists to ever walk the earth," she said as she introduced Prince.

The 12,000 attendees at the MGM Grand Arena went nuts as the iconic soul artist emerged from backstage, donning '70s-inspired attire—an afro, big-framed, gold metallic glasses, flame-print shirt, turtle neck, and silky, yellow bell bottoms that matched his guitar.

Billie Joe Armstrong does bill himself as a punk-rocker. So swearing, ranting, cussing out Justin Bieber, cussing out the audience and organizers, and smashing guitars are pretty much par for the course. Right?

It'll certainly be long remembered by anyone who was attending the iHeartRadio Music Festival in Las Vegas, as well as plenty of the millions who were watching Yahoo!'s live webcast.

The Friday night bill was full of superstars allotted 25-to-30 minute sets, including No Doubt, Usher, Jason Aldean, and Bon Jovi. The exception was Rihanna, whose post-midnight closing set, full of elaborate, Egyptian-themed production values, was slotted for 45 minutes. But at 11:55, 21 minutes into their half-hour, Armstrong, looking at the Teleprompter that counted down Green Day's remaining time, started in on his nuclear-level freakout. ""They say we got nine minutes left! I say boo to that f---ing s---!"
