Hey! I don't know if this has already been done (I didn't see anything really in a search) but as I listen to music, if I think it relates to Animorphs in some way I'll add it to a playlist in Spotify!
I've shared this playlist, and so I think it should be able to be added to by other people, so if you have Spotify you're welcome to add songs! (hopefully it works, lol)
I'm ... honestly not sure how the Spotify URL options work so I"ll just...give all of them.
HTTP link:
http://open.spotify.com/user/1282809903/playlist/6Z8ymnSKx7eTvdPu9Qmfa8 (I think with this one, if you don't have spotify you can still listen to it? I'm not sure)
Spotify URL: spotify:user:1282809903:playlist:6Z8ymnSKx7eTvdPu9Qm
fa8
And if you don't have Spotify/don't want to add to the list you can just leave songs here and I'll add them!
