well, of course.
if your music formats can not support by your music folder, you need to convert them to the formats acceptable to it....moyea video converter can convert among almost video and audio formats with ease, so you may try...
Support to import almost all video, audio and images files for editing and converting. With it, you can trim, crop, add watermark and effect, replace the original files’ audio, flip original video vertically and horizontally, and then convert it to other formats for playback on iPod, iPhone, PSP, Xbox, Zune, Creative Zen, cell phones and so on.
In addition, the output videos can also be imported to iMovie, Final Cut Pro for further editing; be inserted to PPT for presentation; or even be uploaded to YouTube for sharing.
