Mariah's catalogue is worth a fortune, do y'all really think she would give away the masters/stems for free?
Is it really though? Many artists' stems are out there readily available for DJs and producers. I just downloaded Ariana Grande's last album's stems the other day. It doesn't affect the sales of these artists. If anything, Mariah's catalogue sales have never been that great. Hell, even The Beatles' stems became available on Rock Band a few years ago. I'm not saying for her to leak her whole catalogue. I'm just saying that I don't understand the need for people to not leak it, but then share clips.
We got a lot of cute remixes of "I'll Be Lovin' U Long Time" with that contest some years ago. I think it would be awesome if we could do the same with her older music.
