Kudos to her and I don't necessarily think this makes her "better" than others who may not have acheived the same feat.

Call me weird, but I have a feeling she knew she was going to win and break the record. Hence why she gifted them with a performance. All night they kept emphasizing "if she wins x amount she will break the record" almost like it was the build up to the ultimate final "artist of the year" award. Maybe it's just me.
