Is the site with music legal?

Question

Copyright

I want to make a website with music. Using the VKontakte "post on the wall" widget, post posts on the site. I mean this widget. Why don't I just want to make a VK group? Yes, because from the site on advertising you can earn many times more. Will it be legal? Can they show me something? The site will be designed for listening to music. And the audio recordings themselves, as I said, I will take from VK using the widget.
It is very important for me to know this, because I do not want to run into problems and sanctions in the future.

Answer 1

It doesn't matter where the original content is stored (Vkontakte, SoundCloud or anywhere else). If you place this content (even through a widget) on your domain and hosting, you automatically become a distributor of content that violates copyright.
