I work over on the Alvin and the Chipmunks Wiki, and while I haven't advertised here (may do so next month), there's no reason to be embarrassed or sorry.

Never listened to much Nightcore but have dealt with people that either confuse the two or misrepresent how a Chipmunks track is created when they attempt to explain the difference. I just seen a video on Youtube that failed at the latter. A real Chipmunks song is sung at a lower speed (each character has a different speed adjustment and sometimes have different singers dependent on the character/generation) and that lyric audio is speed up to generate the voices. The instrumental is then added to the voices (if the music is speed up and/or the pitch/tempo is changed then it's not a proper Chipmunks version. If done properly, it still wouldn't be official given the franchise has release covers and original songs. Fan "Chipmunks" songs (quotes used because the majority of fans fail in technique) generally just modify the pitch of everything and usually sound horrible because the pitch is way too high and the music is distorted. As a result, people hear these versions and assume incorrectly that that's what the franchise is.
