Hi All I have recently discovered after updating dBpoweramp to 17.5 that it now has _cdgap and _cdindex in the meta data tags written. This seems to be only on some CD's.

I don't really understand what they are and why only on some CD's. Is this a new field in the tags? I don't see a way to turn them off.

Could someone tell me what they are and why only on some CD's and if they need to be there? Many Thanks!
