I thought that cluster worked on the album name as found in the TAG? So if no album name, there is no cluster.
Here is an example workflow of mine when tagging some MP3 files that came from the some old sources not ripped by me.
I dropped three albums onto the Left Panel.
Tracks with MBIDs immediately “Leap to the Right”.
Pressing CLUSTER (Put your hands on your hips) takes the rest and gathers them in groups based on the MP3 Album TAG. This also means a Disc 2 that has different tagging splits in to two clusters.
Next I’ll select one cluster at a time and hit SCAN to attach AcoustIDs. (pull ya knees in tight?)
The album will now Leap to the Right, but as it will probably select the wrong version of the album, I now highlight that album on the right and use Lookup in Browser followed by the TAGGER button to select exact release I want in my tags.
With the example I just chose for the test I got an odd result. It is an 8 track version of a release. Original had 7, a later had 8, but Picard selected one with 10 instead. Hence the need of the TAGGER button on the web page to get the correct option.
Now that the TAGGER button has selected the correct release and pushed it back to Picard I need to go find the files on the Right and push them into the correct Release. (I assume that is the pelvic thrust steps of the Time Warp)
Now I can hit SAVE and…
Its back to the left… and select that next album. This time a Release that split into two clusters due to it being a “deluxe” re-release with tags showing a different album name for disc 2.
I hit SCAN… and ARGH!!! stuck in LIMBO. I get two matches, release splits in two… first half matches to the original single disk release, and the second disk is stuck on “[loading album information]” as it grabs 23 image files… so I don’t even get a clue as to which version it is going for. (It did match the correct Deluxe CD2)
So I hit Lookup in Browser again and make my own choices while waiting for that art to download…
Returning to Picard I drag that wrongly matched disc 1 down to join disc 2 of the Deluxe set. Check the files look right. And hit Save.
Maybe this will work smoother if I put on my drag outfit like Dr. Frank-N-Furter?
The main point being it is clearly getting the matches correct, but my bias to using the SCAN button leads to AcoustID matches of the wrong releases when deluxe editions are involved.
(And yes, I know I could skip the art on this initial run, but for that I’d need to keep flicking an option on and off)
