Hey, all! Bumping this post as I've added another unknown track from one of the Tiger cassettes released in the early 90s, which (like a few others) may possibly come from a digital keyboard/synthesizer (i.e., Yamaha, Casio, etc.) This leaves us with 33 unknown tracks left to identify for both all 2-XL titles.
To summarize, the Mego 8-track tapes from the late 70s/early 80s utilized music from the Emil Ascher library, taking from the following labels:
Amphonic Music
KPM Music
Bruton Music
Musique Pour L'Image
Parry Music
Standard Music Library
Studio G
Ultra Music Services
Plus, they also used tracks from Capitol Production Music's Media Music catalogue for some of the early tapes.
By the 90s, when Tiger Electronics produced new tapes, they not only used KPM, Bruton, Parry, and Amphonic tracks, but also began using De Wolfe Music, sourcing from both their vinyl and CD catalogues.
Here is the link again for all the remaining unknown tracks (8 from the Mego 8-track cartridges and 25 from the Tiger cassettes): dropbox.com/scl/fo/jevq60nw2cbzuay4pk0s8/h?rlkey=n0innvvvfo9wuwxtptkhj0mn3&dl=0
