Any legal way to upload songs to your website?

Only if they get the permission of the rights holder - or you move to a country with extremely lax intellectual property laws. (even then precedents have been set in the past where the content of a website has broken the law in the country in which it was viewed but not the law of the country in which it was hosted)

Re: Any legal way to upload songs to your website?

Short answer: no.

Long answer: legally, you can only use recorded music on your website if: (1) the amount of music that you use is small enough to constitute a "fair use" of that material under the copyright laws (for complicated reasons, that's not likely); or (2) both the underlying copyright in the music (the (C) copyright) and the performance copyright (the (P) copyright) are in the public domain; or (3) you've obtained permission from the copyright owners to use the work.
