Have we really been living in a Princeless world for eight years? It doesn't feel like it. With every passing year, Planet Earth feels more of the magnitude of the Purple One's unbelievable accomplishments. Which includes the sheer body of work he left behind: his rumored mountain of unreleased material aside, have you heard all 39 of the albums he did release?

Yes, Prince Rogers Nelson was an impressive triple threat, and we'll likely never see his like again. In pop and rock history, some were wizards in the studio, but lacked charisma onstage, or vice versa: Prince was equally as mindblowing in both frameworks.

His iconic, GRAMMY Hall of Fame-inducted 1984 album Purple Rain — a soundtrack to the equally classic film — turns 40 on June 25. Of course, crank up that album's highlights — like "Let's Go Crazy," "When Doves Cry," and the immortal title track — and spin out from there to his other classics, like Dirty Mind, 1999, and Sign o' the Times.

To get a full dose of Prince, though, you've got to raid YouTube for performance footage of the seven-time GRAMMY winner through the years. Here are seven clips you've got to see.

Feast your eyes on Prince, the year Purple Rain came out. With guitarist Wendy Melvoin, keyboardist Dr. Fink, drummer Bobby Z., flanking him, even suboptimal YouTube resolution can't smother the magic and beauty. Check out this killing performance of Purple Rain's "I Would Die 4 U," where Prince's moves burn up the stage, with Sheila E. as much a percussion juggernaut as ever.

"Little Red Corvette," from 1982's 1999, has always been one of Prince's most magical pop songs — maybe the most magical? This performance in central New York state borders on definitive; bathed in violet and maroon, caped and cutting a rug, a 26-year-old Prince comes across as a force of divine talent.

"I always laugh when people say he is doing a cover of this song… It's his song!" goes one YouTube commenter. That's absolutely right. Although "Nothing Compares 2 U" become an iconic hit through Sinead O'Connor's lens, it's bracing to hear the song's author nail its emotional thrust — as far fewer people have heard the original studio recording, on 1985's The Family — the sole album by the Prince-conceived and -led band of the same name.

Let it be known that while Prince could shred with the best of them, he could equally hold down the pocket. This Vegas performance of "1+1+1=3," from 2001's The Rainbow Children, is a supremely funky workout — which also shows Prince's command as a bandleader, on top of the seeming dozens of other major musical roles he'd mastered by then.

Words can't describe Prince's universe-destroying solo over the Beatles' "While My Guitar Gently Weeps," in front of an all-star band of classic rockers including Jeff Lynne, Tom Petty, and George Harrison's son, Dhani. At song's end, Prince's guitar wails for a few more rounds, he tosses his Telecaster into the pit, and he struts offstage. We'll never see his like again.

If you're the type of Super Bowl devotee who skips the Halftime Show, please — make time for Prince. When he digs into the trusty "Let's Go Crazy," it's hard not to follow suit. With fireworks blazing, and the Love Symbol brightly illumined, Prince arguably outshined the football game — as he tumbled through inspired cover after cover, by CCR, Dylan, and more. Naturally, he crescendoed with "Purple Rain," augmented by the drummers of the Marching 100.

At Coachella 2008, Prince offered a bounty of karaoke-style yet intriguing covers — of the B-52's ("Rock Lobster"), Sarah McLachlan ("Angel"), Santana ("Batuka"), and more. Chief among them was his eight-minute take on Radiohead's (in)famous first hit, "Creep," with a few quixotic twists, including flipping the personal pronoun I to a very Prince-like U.

"U wish U were special, / So do I," he yelps in the pre-chorus. Oh, Prince: to quote the radio-edited, de-vulgarized chorus of "Creep," you were so very special.\
