Actually, uploading a DJ set on Soundcloud is against their ToS because those mixes contain songs that are copyrighted. Soundcloud is not a good place to upload mixes and that's why there's currently a huge rage between DJs and Soundcloud's team. Basically, the product became big enough to care about copyrights. If you're a DJ, you don't have a right to distribute your mix as a free download if it contains a song copyrighted by a third party.

I suggest you to check out Mixcloud. It's a service made specially for uploading mixes, but it doesn't allow you to download them for the reasons I said earlier. It's also free and does not require you to sign up for an account.
