itunes question

[geeman]

why does itunes have duplicate listings of several U2 videos .... Vertigo, Sometimes you can't make it on your own, Beautiful day, and etc. I can understand the 2 versions of Original of the species (live and original ) but the others seem to be the same video listed twice

 

[dr. zooeuss]

is it due to their being on multiple albums? maybe whoever listed them on itunes was unsure if they were identical and listed them twice...
