Ok guys, Listen.
My mash-up contains a fusion between
Single Ladies (Bodybangers Remix)
And
Gotye & Kimbra vs Bodybangers - Somebody That I Used To Know (Slider & Magnit Mashup)

Because these 2 tracks has the same instrumental and different vocals which are very good,
I decided to fuse them.
These 2 songs are good and I didn't know which one to play because they have the same instrumental.
Then I just decided to stop thinking about it and just fuse them together.

As you can listen,
The mash starts with Single Ladies (Bodybangers Remix)
And then it goes to
Gotye & Kimbra vs Bodybangers - Somebody That I Used To Know (Slider & Magnit Mashup)

So there isn't anything that I've coppied.
For me it was a question of efficiency.

Btw you can talk Russian with me, I understand all of you guys,
I just dont have russian in my pc.
