YouTube: Matched Third Party Content? 10 PTS!?

[Ruby]

I recently uploaded a recording of my school's orchestra playing Schindler's List Theme and then later there was a notification that said "Matched third party content". I know it's not much to worry about, but I really want to get this straight: Did the ContentID mistake the orchestra for a recording of already published content or we aren't allowed to do covers of a song? The notification says:
"Theme from "Schindler's List"", musical composition administered by: UMPG Publishing""
I really want to file a dispute but what if they reject it and my account gets banned?

Someone please tell me what I should Do!! We, the orchestra, played it! not a stupid publishing company! why do they own it now.....

Id just leave it, whoever owns the copyright to schindlers list theme probably was notified and either they don't care or they saw it was a cover, you don't have anything to worry about
