I don't think I was clear in previous posts. I'll try again.
The single file flac and vorbis album files I sent you will play with VLC, but the cue file is ignored. The file plays as if it is one track, technically this is accurate it is just one big audio file, but people with one file albums with cue embedded or alongside the audio file generally want the media player to act as if the single file album is a real album with many tracks. Being able to skip between tracks and see artist album track name for each song is important. The way VLC is not it is like watching a VHS film with no "chapters", it sucks when you want to pick up where you left off, or get to your favorite scene in the movie.
There is a FOSS audio player that is inspired by foobar2000 called DeadBeeF, I never used foobar2000 so I don't know what I missed as I've been using the Mac OS mostly in the last 4 years or so using COG or VOX. Apparently DeadBeeF is amazing in supporting .cue file and most of the music formats. In my tests DeadBeeF played single file albums with cue perfectly in mp3lame, wavpack, flac, alac, vorbis (aoTuv) formats, my guess is it will do other formats as well such as aac wav and so on. DeadBeeF has got the wow factor too, you can re-order the "tracks" of the single file album on the fly while music is playing and use all the regular playback functions like shuffle, random, loop, mix tracks among several single file albums, it is very robust and lightweight.
The program is released under a GNU 2 license, thinking VLC devs could look at the source code and perhaps use some of it.
