What are some songs you didn't know were covers + not originally sung by the person that you attributed to?

An example is "It's My Life" by No Doubt. Clearly attributed more to ND than to the original singers, Talk Talk.

Edit: Also similar, songs you didn't know had a sample of another song in it? E.G. Hung Up By Madonna heavily using an ABBA sample.

"If I Should Fall Behind" was always one of my favorites from Faith Hill's Breathe album.
I learned earlier this year that it was written and originally recorded by Springsteen.

Not my case, but many people didn't know that "Invisible" by Ashlee Simpson was a cover

Torn by Natalie Imbruglia is apparently a cover, had no idea until a few months ago.

inb4 I Will Always Love You
But for me, I had no idea I'm Every Woman was really Chaka's song, no idea Without You wasn't Mariah's song & Still in Love (Kissing You) was a song by Des'Ree.

I didn't know My Prerogative was Bobby Brown's too.

I Turn To You

My Prerogative, I Will Always Love You

I Will Always Love You (Dolly Parton) Whitney just covered it

This Woman's Worth (?) by Maxwell I was heartbroken when I found it was cover song!

adele's lovesong

"Try" (covered by P!nk, originally by GoNorthToGoSouth)

I Love Rock N Roll has also been covered by everyone and their mothers

'Taylor Swift's "Untouchable".

I thought it was Britney's original when I was like 4/5. I also thought she said "Put another dime in the juicebox"

I totally thought Joan Jett was the first person to sing it for the longest time Also Respect by Aretha Franklin was originally sung by Otis Redding?!

I Can't Get No Satisfaction - Britney Spears

Miley Cyrus, these four walls. I never knew it was a cover....
