ok for your first example, overwerk basically edited the same sample used in madonnas song.

and for the second idk, but theres a possibility that the same samples were used.

A lot of songs that sound the same are intentional for the latter song (see: 70% of rap songs).

Every nickleback song, ever

the first song you listed was sampled, obviously, so can we do that? haha.

ourvais - some funk https://www.youtube.com/watch?v=-_QZlnd-Vw8
kurtis blow - the breaks https://www.youtube.com/watch?v=5ZDUEilS5M4

bruno mars - treasure http://www.youtube.com/watch?v=zxXBL7wYjLI
breakbot - baby i'm yours http://www.youtube.com/watch?v=ahdH8eTydWY

pretty much every pop song in existence in one form or another takes a piece of Pachelbel's Canon in d.

pretty much all jason derulo songs and an old song.
http://www.youtube.com/watch?v=pV36OEBWRvU Jason Derulo "ill fight for you"
http://www.youtube.com/watch?v=RdBcfRhzzAA Toto "africa"

http://www.youtube.com/watch?v=pBI3lc18k8Q Jason Derulo "Whatcha say"
http://www.youtube.com/watch?v=UYIAfiVGluk Imogen Heap "hide and seek"

I mean seriosiy I thought there were laws for this.

Give 3 examples on that pls

i think for the last two examples there was an agreement made between the two artists, i.e, imogen heap takes a cut of the money made by jason derulo, or something else idk

Not to undermine the purpose of the thread, but this is a pretty cool site for stuff like this http://soundsjustlike.com/

Both are wellgudm8.

Interestingly enough, that part is originally from an 1979 ABBA song (http://www.youtube.com/watch?v=XEjLoHdbVeE)

The Hollies: Air That I Breathe
http://www.youtube.com/watch?v=WhBqkxDvbHs

Radiohead: Creep
http://www.youtube.com/watch?v=XFkzRNyygfk

The hollies actually sued radiohead over the song because it was so similar and the hollies now get partial credit for the song.

"almost the godfather of pop music because we've all used that in our own ways for the past 30 years".

It's abba original sample, to show that the original song is not from Madonna

The very brginning of the intro to Metallica's Fight Fire with Fire

http://youtu.be/xjlgUx7_aN0

Sounds an awful lot like the Brokeback Mountain theme song in the very beginning.

I've got a few of these:

www.youtube.com/watch?v=u-HUHkR6l8E -"No Sign of Life" by OK GO
Has an almost identical construction, composition, feel and pace as.
www.youtube.com/watch?v=qrdpliMfoAM -"Where is My Mind" by the Pixies

The Chorus of
www.youtube.com/watch?v=o0c-kC8xZ-I -"Love Drunk" by Boys Like Girls
is a combination of parts of the Chorus of
www.youtube.com/watch?v=ueUXycqAcJA -"Somebody Told Me" by The Killers
and a short section of the into of
www.youtube.com/watch?v=gGdGFtwCNBE -"Mr. Brightside" by The Killers

You can almost swap the lyrics of
www.youtube.com/watch?v=YgSPaXgAdzE -"Loser" by Beck
and
www.youtube.com/watch?v=aq8pMNX-KWA -"Pepper" by The Butthole Surfers
provided you adjust the tempo of the words.

Papa Roach - Last Resort: http://www.youtube.com/watch?v=Hm7vnOC4hoY
Iron Maiden - Genghis Khan (1:46): http://www.youtube.com/watch?v=4QxiQ2LRiz0

All three of these use basically the same riff.
Venom - Welcome to Hell: http://www.youtube.com/watch?v=4e0VvHZMaTs
Mercyful Fate - Curse of the Pharaohs: http://www.youtube.com/watch?v=ld3PWrd8sbE
Iron Maiden - 2 Minutes to Midnight: http://www.youtube.com/watch?v=7sXPmz9b4lM
