Playlist support will come in the future, when I pick up ctrmus again in two months after exams, etc. All MP3 files should be playing properly, so the fact that some of your MP3 files aren't working means that there is a bug in ctrmus. Could you send me a link to one of those MP3 files that aren't working via PM please? That way I can test your file and see what is going wrong.
I have opened an issue
here to keep track of this bug.
Ok thanks for reply
I attached "Hatsune Miku Soft - Hello How are you (haro hawayu) PV (English Subs)" onto this comment, if you find it works i'll try downloading the cia straight from your site instead of "titles.db". Thanks!!!
