Hopefully some of you find this information useful if not I apologize in advance. I've learned a lot since I started reading these forums and I thought I'd try and contribute a small piece of information I have. It's pretty simple and short but you might like it. To avoid a 'Matched 3rd party content' notification on youtube you must change the pitch of the audio file before uploading it. This can be done in Adobe Audition or Premiere, as well as plenty of other audio intensive programs. Usually tweaking it a few semitones in either direction should do the trick. + or - 3-6 semitones should be fine. Hope this helps someone out there, like I said I've learned so much from this place already. Thank you all. PS I hope I posted this in the right place.
