It’s been an issue for a couple months now but I find this commonly a problem when it’s not official channels or an official singer. For example if I were to download a Kpop song from GOT7 or a song by Arianna Grande, I could download/favorite those songs even as lyric/color coded songs. However, for cover artists or OST songs or even mixed/remix songs I can’t download/favorite them and they won’t even play. Please fix this as soon as possible because it’s depressing to not be able to download any song I want without having these kinds of problems.
