People who haven't heard Memoirs aren't going to think the features sound copy and paste because they haven't heard the originals.
"if she really wanted to do this right, she could have gone back and changed them up a lil in these 3 months like some people have already said."
Mariah makes way more music than most popular artists could ever dream of. She worked her ass off for Memoirs, and once that was done, she had other things to
do. Besides, she obviously loves the original tracks on Memoirs, so she probably didn't want to change it that much. She doesn't want to give people a
completely different album. She wants more people to get Memoirs, and if this is what she has to do to get more people to hear her music, then so be it.
