To add to my own message, if you know which manufacturer you are looking for, some manufacturers have fairly decent searchable websites that offer much information.
Some examples are:
SBI/Abraxa/Aardon Aardvark/MPME
The SBI karaoke website (
https://beta.sbikaraoke.com/) for instance, has a very neat search feature hidden away near the bottom.
Once you narrow down your search and choose your format and version (Abraxa vs MPME vs SBI vs Aaron Aardvark, etc.), it will show the track ID information as well. So, for those manufacturers, if you know what tracks you want information for and just need their IDs, then that is also a way to do it.
Karaoke Version
Similarly, Karaoke Version has a substantial amount of information on its website, and if you want to parse through its catalogue, they have an up-to-date XML file of all its available tracks (along with track IDs, etc.). I think the XML file can be downloaded from this link:
https://www.karaoke-version.com/misc/catalog/karaokeversion_catalog_en_USD.xml.zip.
The list goes on. Unfortunately, uniformity in global karaoke indexing is a tougher challenge than one would expect!
P.s.
Regarding the links I shared earlier, I noticed that OpenKJ seems to be indexing the newer Zoom and Sunfly tracks as opposed to iCroons and Karatrack, but does not seem to show as much (if any at all) KV stuff.
