So, I attained most of my music through er...less scrupulous methods. More specifically, I use RealPlayer to download Youtube videos of the music, converted them to MP3, and then the details edited in iTunes. If I were to get iTunes Match, would I run into many problems with the service "matching" the music? A few songs may have the beginnings/endings slightly cut off, and the quality may be a bit less than an MP3 obtained from somewhere like Amazon MP3 or The Pirate Bay.
