peace and respect to all

okay currently i have been trying to burn music files from winrar on to a disk. here's the thing i successfully download three albums however the problem comes in whenever i try to download recently the disk reads as mixed media disc which only is playable on the computer or a gaming console what am i doing wrong?

also when i insert into my drive it reads as a dvdrom (think one of the reason this is because i try to burn a dvd yesterday)
