I found this info, surprisingly, on a playlist of songs from the Tandy version by VintaGamers Paradise. And it's no surprise it took me so long to find this; the videos have less views than mine somehow, even though it's a relatively well-known channel. After looking further into it, other sources agreed with the names, and I found on the Cutting Room Floor that these are the names given to the tracks in the sound test on the DOS version. Though it does mention that these are more descriptors of the tracks than actual names, they are the closest we have, and they are the only way to identify a song that plays at different times in different versions, other than cumbersomely listing where it is on both sequences.
