The MLP Unofficial Soundtrack, a soundtrack for My Little Pony: Friendship is Magic by CaptainComedy (seasons 1–3) and RainShadow (season 4).

Seasons 1 and 2

Note: This is an original torrent, specifically created for Rainwater Tornado based on existing files.

Seasons 1 and 2 are available on Mediafire.

There are two torrents available, one with the files as is and one with the archive files unpacked and organized. (The archive files are unpacked with a shell script; refer to the comments in the script for more information.)

(The MLP Music Archive had different torrents for this soundtrack, but these seem to be “lost.”)

Season 3

Note: This is an original torrent, specifically created for Rainwater Tornado based on existing files.

Season 3 is available on Mega (direct links on Tumblr):

Season 4

Season 4 is available on MediaFire (from the description of a YouTube video [use “Inspect Element” to view the full description], via the shortlink https://bit.ly/mlpseason4soundtrack).

According to the video description:

The soundtrack is split into 2 downloads. This first contains discs 1 & 3, which have all of the songs, backing vocal versions, and instrumentals by Daniel Ingram. The second download contains disc 2, which is the complete season 4 BGM collection by William Anderson.

Downloads are available in high-quality MP3/AAC, or in lossless ALAC/FLAC, and are available as either a direct download or torrent. The download also includes a 54 page digital booklet with images from the show, as well as analysis/commentary on every song and every episode’s score, diving deeper into reoccurring themes, musical styles, and musical callbacks. It’s a nice read, as it’s easy to overlook the continuity the score of the show has.
