Love This!!

😘

I like this a lot and I normally don't even like Gaga

Seems to work quite well! I wasn't sure how a Saturdays/Britney mashup would work, but this one is good.

Another fail attempt to revive an old forgotten gaga song. NO thanks. thumbs down cause of the Gaga vocals

Katy Perry for Romania :))

Suprisingly Catchy

Amazing !!!

they should totally collaborate, 2 of my fave musicions

"this beat is sick" gaga is right, it is , muse can make EVERYTHING BETTER THEY EVEN MADE LADY GAGA BETTER I LOVE YOU MUSEEEEEEE

this is the only mashup of i kissed a girl that actually sounds good and works well :)

SPICE GIRLSSSSSSSSSSS FOREVER!

It's basically the same song anyway

aww sweet!

Lady Gaga tem cabelo silvestre

LOL! nice comment.

this song is actually good!!!!!!!!!

Spice girls wrote all their own music, so please get your facts right. I love Gaga and the Spice girls but those girls who had no help as they left their manager with no contract and worked their way up properly had the biggest effect on popular culture in the last 30years.

awesome!

Buuuu

gahh mashups are just so interesting.

excellent mix :D

You did not tune Katy's voice up to the melodie.

KATY PERRY

WOW

Katy Perry ma Lady :))

wo0ow! i kissed a girl is the best s0ng!! like if u think the same!

WOW these go together AMAZINGLY!! I'm so happy I stumbled upon it :D

it's an unfair comparison cos it's 5vs1 and people would have grown up with spice girls and they had people writing some songs for them. gaga on the other hand wrote all her songs and earned her own fame without any help and it was hard to get into the music industry before she became gaga. GAGA ALL THE WAY!!!

. . . YES.

Both are good.But BRITNEY SPEARS IS JUST THE BEST,QUEEN OF POP!(:

Damn this is KEWL!!! :)

Muse makes it decent :']

well finally lady gaga says something right this beat IS SICK

@elikayal They didn't steal anything from each other. If the time and keys match, they can flow very easily together. When mashing music, you'd see that MANY songs go flawlessly together and sound great, even though they're COMPLETELY opposite. For example, just the other day, I discovered this mashup of Lady Gaga's Bad Romance and Muse's (British rock band) Time is Running Out. They fit together so well... amazing x'D If you're interested, it's called Romance is Running out (youtube it!)

THE SPICE GIRLS FOREVER!!!!!!!!!!!!!!!

O.M.G the same beat exactly who stole from the other ??????????????

Oh my jesus I think my ears just had an orgasm.

even the orig supermassive black hole doesn't sound like a black hole

Great mix :D

key's don't match up

gaga and muse are completely different genres of music. so don't even waste your time comparing. they're both amazing in thier own ways!<3

Spice Girls Rules! The queens of the pop!!

@noggy92 that will be interesting

perhaps this is what the grammys is gonna be like... apparently Muse is collaborating with Lady GaGa, should be....interesting. anyway Matt has always said that he likes Lady Gaga so it could be cool MUSE rocks :D

Love the guitar in the chorus!

So sweet! The "If You Seek Amy" beat makes this song so totally Epic!

@ryanloveskansas Lady gaga doesn't even compare to Muse

The Veronicas didn't made this song! this was made for a fan! so shut up and stop saying that The veronicas stoled this song .i.

who kissed amy lol
