Searching Discogs

This is really frustrating

I use DB Poweramp for ripping and i am adding a 900 plus cd collection to discogs

Certain titles i cannot find them on discogs no matter how i construct an advanced search there

But when i put the cd in dbpoweramp it nearly always gets the tags from discogs i have asked the question on the discogs forum IGNORED i didn't get get a better response on the dbpoweramp forum

So how the hell does it work, i know you guys are very knowledgeable and someone here knows the answer to my question, please put me out of my misery and tell me.

Keep it simple though, like me

Thanks as always
