Recently, I found that Apple Music no longer has this album. Having just gone through the process of creating the page about The Gospel at Colonus (gospel.html), I created these mp3s and this page. In this case, I got the files from the Pirate Bay via torrenting, as flac files. So I don't know their provenance.
The following is the result of these efforts. I hope someone enjoys this music like I do. First, the .m3u file: Echoes/Echoes.m3u
On My Mac, that plays in Safari via http streaming, which is pretty satisfactory. If you save it, then open it, Apple Music, opening that creates a playlist called "Internet Songs" which has all the songs. It is streaming them though.
To actually add these songs to your library as an album, download the zip file, it will create a folder called Echoes in Finder. In Apple Music, go to File->Import, navigate into the Echoes folder, and select all (Cmd-A) and open. This will create an album called Echoes by Wally Badarou with the songs in the correct order.
I don't know what other players will do with it.
On Windows, clicking on the m3u file also streams it. If you download the zip and extract the files, you can follow a similiar process in Media Player of Adding the folder to your Media Library. The ID3 tags will have it as an album with track order and song names.
The .mp3 files:
01 Keys.mp3
02 Hi-Life.mp3
03 Mambo.mp3
04 Voices.mp3
05 Canyons.mp3
06 Endless Race.mp3
07 Chief Inspector.mp3
08 Waltz.mp3
09 Jungle.mp3
10 Rain.mp3
Here they all (the mp3) are in a zip file: EchoesMp3s.zip
