wow, so im not the only one?
Im replacing my mp3 albums now with backups i made a while back . Sadly, i didn't backup any of the music i downloaded in the past year

but not all of the albums were damaged, and i can easily just copy them from the actual cd or redownload.
I noticed that many of my mp3's that were cropped or whatever... all the other mp3's in that folder were as well. Example:
I have "green day international superhits". Every mp3' in that albums folder was cropped, and some 15+seconds in.
like my favorite green day song "basket case"

. was cropped all the way to the second verse.
It makes me mad, because i didn't know this was possible or would happen, but at the same time i was using a beta product, so i cant really blame Microsoft, but still. Shouldnt ever of happened.
So i suppose for the next few months or year, i'll randomly find songs that were half deleted, and have to replace them on the spot with the original files, but its life.
