Thank you michael-collins. :]
I need to benefit the most out of your comment. Please bear with me.
Can you please elaborate more on this (not forgetting to pinpoint the time when (at least the most notable ones) such things occur)?
If you mean the wrong notes are not exactly similar to the original, then I think that's what the rules here are insisting on telling not to copy but try to differ within the given song structure. Also, when not using anything as a base in your project (e.g midi, as I've constructed this mix by listening to the original), you're not (and probably won't) 100% being exact regarding the notes.
Please, correct me if I'm understanding wrong.
Again here, I need to know the most noticable areas (with more elaboration if you don't mind).
At the end, can you please highlight things that should not be changed or severely altered in the remix?
Thanks again michael! :]
