I have a three-step process for audio BDs. Decrypt the BD using AnyDVD HD to an ISO, then mount the ISO and use DVD Audio Extractor to rip the tracks to FLAC.
DVD Audio Extractor will identify the type of tracks contained on the BD or DVD (stereo, 5.1) and also the codec used, if any (PCM, DTS-HD, etc.). One caveat, DVD Audio Extractor can only extract the DTS Core from DTS-HD tracks so I always select PCM if given a choice. I have about 25 audio BDs (Yes, Pink Floyd, Steven Wilson, Tom Petty, etc.) and most of them contain PCM tracks in addition to DTS-HD so that's usually not a problem. If you need to extract DTS-HD, there is other software that can be used. Once extracted and converted to FLAC, I then use MP3tag (or you could use MC) to tag and add cover art.
I also like to keep decrypted ISOs of my concert and music-oriented BDs that have video. MakeMKV is fine for movies where there is one main feature, but it's a pain to use for a lot of music BDs which can have many titles. For example, the two Beatles 1+ BDs have about 30 titles each. I prefer to have 1 ISO of each disc and then use the BD menu to either select the track or play the BD straight through.
