What key signatures are these songs in?

Hello!
I am a new user.
I am confused with this kind of music. They play with the keys and harmonies and I cannot determine what key signature are the songs in.

I will put the artist and titles in order to listen to it and help me to determine the keys:

Pete Belasco - Love train

Pete Belasco - Love is

Pete Belasco - Who's the man

Jazeboo - Smooth Diamond

I think this site block links in our posts, so I put artists and song's titles. All is in youtube and you can enjoy it by going there.


(The last song I think is in the key of A Minor, but why I hear the chords B Bimol Major and D 7 Major at the end of each part?. These two chords are out of the key of A Minor. Try to explain me it)...

Answers, please...

Hi; the song Whos the man has a progression like the following (the Key seems to be Cm#):

C#m7add9 to Fmadd9 to Em7add9 to D#m7add9 to G#7b13

i am no expert in that kind of progressions, jazz-like or something but it seems like it could be analized following some inner line within the progression; for instance, the line; B C D (F#-D#), B to C (upward semitone/halftone) C to D (upward tone), D to F# (3rd skip) and F# to D# (tritone skip).

taking the upbeats of the chosen line, gives B D, that is an upward minor 3rd.

the song Love is is in the Key of C#: its easy to see that the bass goes like: C# E B A...etc.

the song Love trais seems to be in the Key of AMaj7 and the basic progression to be AMaj7 D#m7...

the Jazeebo song has the progressions: Am-Dm (x3) plus bB-D; and then: Bm-Am (x3) plus bB-D.

Love is: Do you mean in the key of C# Major???

Yes. These jazz-style songs have complex key signatures. Thank you very much for the answer!. Love is has in the chorus the key of Gm# I believe...

Indeed...the chorus does G# G F# F (taking the Key to be C#, the chorus' G# meant to be the Dominant-V- of the Key).

Ps: The line cited above was meant to be B C D (F#-C) instead of B C D (F#-D#)...
