Top 10 Songs Where You Most Likely Heard a Cover Version Before the Original

This can happen a lot. You hear a cover of the song before the original song itself. Now I'm not saying that any of these covers are better than the original (some are and some aren't). What I mean is these are songs you most likely heard a cover of before hearing the original.
The Top Ten
1 I Love Rock 'n' Roll - The Arrows

You probably heard the Joan Jett version or if you are unlucky the Britney Spears Version ugh...

If you're unlucky you heard the Britney Spear's version first...

2 Sweet Dreams (Are Made of This) - Eurythmics
3 Knockin' on Heaven's Door - Bob Dylan
4 All Along the Watchtower - Bob Dylan
5 Dream a Little Dream of Me - Ozzie Nelson & His Orchestra

I first heard Blind Guardian cover of 2007 while the original is of 1931...

6 Behind Blue Eyes - The Who

If you are unlucky you probably heard the Awful Limp Bizkit cover

7 Without You - Badfinger

You've probably heard Mariah Carey's cover first, and might think that Harry Nilsson's version is the original.

I heard Harry's version first.

8 The Wizard - Uriah Heep

I first heard the cover by Blind Guardian.

9 Cum On Feel the Noize - Slade
10 Dazed and Confused - Jake Holmes

The Newcomers

? Got My Mind Set on You - James Ray
? Make You Feel My Love - Bob Dylan
The Contenders
11 Hallelujah - Leonard Cohen
12 The First Cut Is the Deepest - Cat Stevens
13 Walking in the Air - Howard Blake

You propably have heard Nightwish's version first.
I didn't by the way, I saw the short animated movie this is from as a child, then years later again as a teenager. I didn't recall it being that depressingly sad.
But that was how I discovered Nightwish, by browsing this song.

14 The Man Who Sold the World - David Bowie

I heard the Nirvana version first, and no disrespect to David Bowie but I prefer Nirvana's version

15 Girls Just Want to Have Fun - Robert Hazard

For the longest time, I never fully realized that Cyndi Lauper's version was a cover. It totally changes the song's meaning.

16 Hurt - Nine Inch Nails
17 I Will Always Love You - Dolly Parton

For the longest time, I actually thought Whitney Houston's version was the original version of this song.

18 Love Hurts - The Everly Brothers
19 It's My Life - Talk Talk
20 Antisocial - Trust
21 Twist and Shout - Topnotes
22 The Sound of Silence - Simon & Garfunkel
23 You Spin Me Round (Like a Record) - Dead or Alive

Who covered this?

24 Turn the Page - Bob Seger

You probably heard the Metallica version first.

25 Venus - Shocking Blue
