Corrupted Files in Splatoon Gamerips

Recently I’ve downloaded and extracted all the files from the most up to date versions of both Splatoon gamerips.

Although I had some trouble with a few of them, I was eventually able to convert them all into MP3 format (either directly or through at least two different formats beforehand). However, there are two particular files (one in each) that appear to be un-convertible.

These two tracks have the same name in both archives:

STRM_World

I’m sure many people are familiar with these ones. If anyone has managed to find some way to convert these two, could I please ask you to share?

Thank you.
