1. The playlist includes every exposition repeat (or other repeat) that Brahms indicated.  That was one of my most important criteria.

2. In spots that require gapless playing between tracks (such as a few of the variation sets and the cantata Rinaldo), Spotify does a very lovely job (unless it
s time for an ad).

3. Both the original and revised versions of the Op. 8 Piano Trio are included (these are essentially two different pieces).

4. The Ave Maria, Op. 12, is given in two versions, one with orchestral and one with organ accompaniment.

5. The piano solo arrangement of the second movement from the Sextet, Op. 18, is included after the entire Sextet itself.

6. The Piano Quintet, Op. 34, is followed by its arrangement as a Sonata for Two Pianos, Op. 34b (for now, not the recording in my guide for the sonata).

7. There are four (somewhat confusing) versions of the Waltzes, Op. 39.  The first sixteen tracks are the original version for one piano, four hands.  These are followed by two tracks, the standard, more
difficult solo (two-hand) version.  There are then 16 tracks for the easy solo version.  Finally, there are five tracks for the waltzes Brahms arranged for two pianos, four hands.  These are numbered 1-5 here, but they correspond to Nos. 1, 2, 11, 14, and 15 of the other three versions (again, this two-piano recording is not the one used in my guide).

8. The Liebeslieder Waltzes, Op. 52, are included in the main version for piano duet with vocal quartet as well as the version for piano duet without voices, Op. 52a.

9. The Haydn Variations for orchestra (Op. 56a) are on a single track.  The Haydn Variations for two pianos (Op. 56b) are on ten tracks.

10. The Neue Liebeslieder Waltzes, Op. 65, are included in the main version for piano duet with vocal quartet as well as the version for piano duet without voices, Op. 65a.

11. Unfortunately, and for no apparent reason, Spotify does not include descriptors or even numbers for the individual piano pieces of Op. 76, Op. 117, Op. 118, and Op. 119 in the Martin Jones recordings.  These descriptors and numbers do appear for other pieces in this box set, so this is highly curious.  I have done guides for all four of these sets.

12. The Romances and Songs, Op. 84, are included in two versions, one for solo voice and one for vocal duet.  These pieces are indicated as being
for one or two voices.  My guide for this group needs to be revised, and it will include the duet version as an alternate when I get to that.

13. The Six Songs and Romances, Op. 93a, are followed by the Tafellied (the drinking glee), Op. 93b.

14. The 11 Zigeunerlieder (Gypsy Songs), Op. 103, are included in the quartet version (sung by a small choir in an excellent recording) as well as in Brahms
s arrangement of Nos. 1-7 and 11 for solo voice and piano.

15. Each of the clarinet sonatas, Op. 120 Nos. 1 and 2, is followed by the version for viola.  Despite the descriptor as
clarinet sonatas, the Zukerman/Barenboim recordings are the viola version.

16. Finally, none of the works without opus number (which have been given WoO numbers--German Werke ohne Opuszahl--Works without Opus Number) are in the playlist.  So no Hungarian Dances (the most glaring omission), no F.A.E. Scherzo, no folksong arrangements.  I may make a separate playlist for the WoO pieces at some point.  I know that WoO 19 and 36-38 are not available on Spotify (only one recording exists of these, and it can only be obtained in a now out-of-print version of the Brilliant Classics Complete Edition).  I think everything else is available.
