A friend just sent me a mail about his project; setting up a website where people can download and listen to music's online whilst allow promotion of artist.

I am involved because I will be designing the website.

Now the problem is, I don't know much about music copyright law.

I sure know you can't just download someone's song and upload it for free online for people to listen and download.

Please I need your advice as he is also counting on me for advice concerning the copyright issue because that was one of the first questions i asked him immediately i read the mail!

Also if you have any other contributions to help the project, that will be well appreciated.
