I have doubts about the Spotify data. Who has listened to 30 million songs? I would put the rent money on 'nobody'. How does one go about finding the key for that many songs using a computer, the only possible way to do it?

- more known the opus, more separate recordings exist (sometime 50s - 100s) which all counts
(btw the latter may corrupt jazz tune statistics on Spotify too)

I think the C# Db anomaly is all the tunes from the 60's in C and D when tuning was apparently optional.
Yeah, I'm looking at you, Rolling Stones

They clearly didn't ask Blooz Daddy guitarists, or there would have been more in E.

Anyway, horns are nice, but no way I'm gonna let them decide what key to play in. A horn player worth his salt has no problems with C, D, G, A....

Spotify has albums by every artist imaginable how can you call it garbage?

Also all my classical listening comes from there and it (Spotify) is invaluable listening resource.
I was talking about statistics, that the top 10 has 30 million listeners per month and the jazz is not dominated there so not dominated neither in the statistics.
@JCat: this explanation also goes for you, my intention was not to degrade other styles than jazz standards.

Oh ok, so that's just a critique on musical taste, not spotify

Here are the refined statistics, where major and its relative minor are in one bucket:
F/D-: 194/37 (23.1%)
Eb/C-: 154/43 (19.7%)
C/A-: 153/8 (16.1%)
Bb/G-: 134/24 (15.8%)
G/E-: 88/8 (9.6%)
Ab/F-: 50/40 (9%)
Db/Bb-: 19/13 (3.1%)
D/B-: 12/1 (1.3%)
Gb/Eb-: 2/9 (1.2%)
E/C#-: 2/4 (.6%)
A/F#-: 2/0 (.2%)
B/G#-: 2/1 (.3%)
-----------------------
Total of 1000 tunes
I've also processed a completely other source of 1350 jazz standards, just for cross checking. I mean it is mainly the same set of tunes, but the source is different, so the typo-s, some key transpositions and potential processing errors could be different, so ideal for cross check the main trend:
F/D-: 240/37 (20.5%)
C/A-: 235/25 (19.3%)
Eb/C-: 204/49 (18.7%)
Bb/G-: 175/27 (15%)
G/E-: 113/12 (9.3%)
Ab/F-: 75/36 (8.2%)
Db/Bb-: 37/18 (4.1%)
D/B-: 23/8 (2.3%)
A/F#-: 10/0 (.7%)
E/C#-: 4/2 (.4%)
B/G#-: 4/2 (.4%)
Gb/Eb-: 1/13 (1%)

Gabor, thanks for providing the stats...0.2% A major...it's getting worse
I quote docsteve: "Horns love flats, strings love sharps."
(My repertoire I was referring to is 90% Jazz standards, but transcribed for solo guitar in any appropriate key decided by me. For rhythm work and improvisation, key doesn't matter.)

I think both based on the Hal Leonard Real Book, but I am not sure
