Yes, so it would seem. I would advise to take it easy though and exercise some caution, rather than merging the lot in one go. Here is my handy-dandy checklist for deciding whether I can safely merge recordings:
- Same recording name and artist
- Similar duration
- Two or more recordings sharing an AcoustID (or several)
- Two or more recordings sharing an ISRC
- Various same year editions of the same album.
- Various editions of the same album with no reasons to suspect clean version, remix, new recording or whatnot.
- Same per compilation liner notes (e.g. when the compilation says “From the album…”)
- Citation of curated discographies either online or in printed form
- I have ear checked all tracks for these 2 recordings.
