Mellow Maestro

The program looks nice, but what has this to do with DOOM?

Mordeth left out the fact that it is an LMP player as well. You toggle between MP3 & LMP mode, & load either file type & hit play.

Forgive me for sounding dense, but isn't LMP a binary data format? In which case it isn't really music. The most common use for LMP data is demos, probably, so are you saying your Mello Player can play recorded Doom demos?

is the web browser like neoplanet?

Yes, it will play Doom demos. & I have no idea what Neoplanet is like. Try it & you tell me. :-)
