floorfilla, I'm sorry, but I have to side with Dylan on this one. There are a lot of "thieves" out there, so rather than get categorized under a mashup thief, you should have contacted S.I.R. or whoever the original mashupper was, and ask for their "blessing" to remake it. Like Dylan said, mashup artists are a small community (getting bigger by the second though), and I'm sure he would have no problem in letting you tweak it. Trying to go the "does he own the original tracks... did he write them? no^^" way is a bad attitude, and I would like to warn you now, an attitude like will only get you banned here. You posted up material, someone gave you their input. You can either accept it, or deny it. That's it. No need to get snippy.
PS: Next time please add a soundcloud link, it is much better to listen that way than having to download a file and listen.
Thanks,
