The Amiga version of SongPlayer 1.62 is available now here. The CDDA management will be improved but you will find a new tag editor for that. The CPU consumption comes back to a low level and a great improvement is the better mp3 support (still no vorbis at the moment).
Another version allows you to use SongPlayer without any hardware hit (full AHI and no filter access). It is well oriented to be used with Amithlon and OS4 under emulation.
