I made a playlist of Hänssler's Complete Bach Edition before (duo to a temporary glitch, most recordings from that playlist became unavailable since this week; Hänssler's digital distributor Naxos told me they were re-delivering them to Spotify). The performances in that Edition were very fine, but few of them are first choices. So I compiled another playlist for the complete works of J.S. Bach, using the best non-Hänssler recordings, from DG (Helmut Walcha, Martha Argerich), Decca (András Schiff), EMI (Pierre Hantai), Sony (Glenn Gould, Murray Perahia), Warner (Nikolaus Harnoncourt), BIS (Masaaki Suzuki), SDG (John Eliot Gardiner), Nonesuch (Lorraine Hunt Lieberson), Harmonia Mundi (Richard Egarr), CPO (Gerhard Weinberger) and many other labels that I could find.
Works in this playlist are sorted by BWV numbers, from BWV 1 to 1128 (discovered in 2008). Works with Anhang ("Appendix") numbers are attached at the end. The BWV catalogue itself is sorted by genre; see detailed list of works in this Wiki page.
Here's the Spotify playlist: Bach Works Catalogue (Bach-Werke-Verzeichnis) (3488 tracks, total time: 168 hours) It works better in Album view. All tracks are available on both Spotify UK and US. There is no such thing as a definite recording of Bach's work, so I used as many recordings as possible (six recordings for the six unaccompanied cello suites, for example), and I will keep on updating this playlist to include more outstanding albums. Look forward to your suggestions.
Happy 327th birthday.
