"Final Fantasy IV OSV" sold over 164,000 copies. It was well received; reviewers have praised the quality of the composition despite the limited medium. Soundtrack Central compared it favorably with Uematsu's later works, especially the soundtrack for Final Fantasy VI, and termed it a "great CD". However, the length of several tracks as well as of the album as a whole was criticized, with reviewers finding it "too short" and disapproving of the early fade-out of some tracks. Reviewers found the expanded and remastered version found in the "Finest Box" to be comparable to the quality of the original album, with some tracks improving in their remake, becoming "deeper" or "sharper" as was appropriate.
