people keep saying soundcloud is a whale when it comes to uploading mixes or whatever. but it was never designed for top 40 mixes and using tracks that believe it or not belong to labels. look around soundcloud, they do not encourage nor promote mixes or mash ups etc. that use copy write material (like some places might). but they encourage the use of recording original sounds and music. its a good platform for people who want to share recorded sounds (of a a band in a garage or a sheep going 'baa') srs... i think its lucky you can still get a mix up on it and use it as a promotional tool to benefit yourself for free. Soundcloud most likely do not want legal threats from labels everyday as much as you or i would in the email inbox. use mixcloud or another site if you think they are whales, or just be grateful a mix or mash up can still go on it. /end rant.
