Soundcloud issue

What is the deal with the mixes on Soundcloud? I want to upload a 30 min mashup but there is copyright infringes. is there a way around that at all? Mixcloud works just fine its only Soundcloud

Don't use commercial tracks.

Change the intro of the mix, maybe make it a mashup of two tracks or something heavy with effects, Soundcloud generaly just checks the first few seconds of a track so you need to change that, so make the intro as original as possible

I had the same issue recently...I put some silence, then delay into the first 10sec of the mix and it worked.
