Q: Hmm so you don't really think there are songs in Lydian? What about Dorian and mixolydian? I'm pretty sure these songs are in Mixo, (or at least use it): "Get Back", "She Said She Said", and "Got to get you into my life" by the Beatles. Speed of sound and clocks by coldplay. Lorde - royals, steely Dan- Black Friday, and don't stop till u get enuff by Michael Jackson.  Songs I know in Dorian (or use it): miles Davis so what, MJ Billie Jean, several Santana songs, get on the good foot James brown, get lucky daft punk,  etc.
A: yes that's right, those modes are perfectly comfartable home modes. by the way, i would consider "get lucky" to be in F#min starting on the 4 chord
