Update: It appears that the folks at customsforge have come up with something that really works, it’s called the Customs Forge Song Manager (CFSM) it will go through your DLC and catalog it by name and artist. It can also export the list to a spreadsheet. – I have downloaded it and it works pretty well.
I am looking for a good way to catalogue 📇 the songs I have, so far, there appears to be no good way to do that. This may be a good project for the future. I wonder if you can find the artist and track name from the song file itself. That might be worth investigation.
