What CD filesystem are you using?
From a shell, do a dir listing on the CD. If nothing shows up there, you probably need a different/newer CDFS.
Yeah, what Matt said.
OR, maybe you can burn a new CD in a format that is compatible with whatever CDFileSystem you have loaded on your Amiga. Modern Mp3 file naming conventions may be incompatible with older Amiga CDFSs. Path and file names may be too long and may contain illegal characters, like spaces.
