Why is there Maroon 5 on it?
And at #1. Have you no shame?

its my favorite song!

i dont make fun of anyones top songs!

All that Beatles doesn't hide the beast that negates this whole list.

Not in order

1.Joy Division - Disorder
2.Jay Reatard - You mean nothing to me
3.Gino Washington - Out of this World
4.Poison Idea - Just to Get Away
5.Ty Segall - Pretty Baby(You're so ugly)
6.Mark Sultan - Beautiful Girl
7.NoBunny - I am a Girlfriend
8.I was a teenage satan worshipper - Candy Candy
9.GG Allin - You hate me I hate you
10.Adolescents - Kids of the black hole
11.X-Ray Spex - Oh Bondage Up Yours!
12.The Isley Brothers - Shout
13.Marked Men - Fix my Brain
14.Digital Leather - Styrofoam
15.Blind Willie Johnson - Dark was the night - Cold was the ground
16.Ebba Grіn - Staten och Kapitalet
17.Stooges - TV eye
18.The Sonics - Have a Love Will Travel
19.Junior Senior - Move Your Feet
20.The Smiths - William It Really Was Nothing

Pointless list. I could make hundreads of top20 song lists with different songs and they would still be just as right as this one.
No Ska, Reggae, pop, Funk, Soul, Hardcore, Doom, Drone or Metal songs on that list for example. Narrowing the listing down to one genre would be much more fruitful.
Narrowing the listing to one genre would be

1. Hammer To Fall - Queen
2. The Invisible Man - Queen
3. The Hurlers - Seth Lakeman

Cant think of any others.
