Say if I have a site that contains videos from youtube. All these videos are MTVs and songs by popular singers. Will Adsense reject my application based on copyright issues and stuff like that?
Easiest way to be approved by adsense in to create a blogger blog (owned by them aka google) and post like 5-10 posts of your own (unique), you will be accepted 100%
www.blogger.com Create a blog with around 10 relevant posts and use that to be approved. Works like a charm.
all you need to do is to make a website which has value, which has unique content whether it is videos, text, images all would be showing adsense ads.
It might be accepted if it is hosted on a Blogspot account, which is owned and trusted by Google. In any case, ask them first. It is a bitch to get approved and banned a month later when payment is due.
I'd say that Google Adsense will not accept such a website because it will not contain original content, and it will be viewed in a negative light.
You will not get approved with this kind of website By the way, you are stealing other people's properties
