I have a few songs that feature 3 or 4 singers or artists on one track, but I can't create a video for them because this feature isn't available. Examples include songs like Bang Bang by Jessie J, Ariana Grande, & Nicki Minaj, Lady Marmalade by Christina Aguilera, Lil' Kim, Mya, & Pink, and other multi-artist tracks. I requested this about 5 months ago but haven't heard anything back.
