Musical question for those who really know their stuff!!?

Question by You can call me Rob: Musical question for those who really know their stuff!!?
Some artists have recorded music on various labels during their careers, but a few artists that come to mind have recorded the bulk of their music on one label (possibly two) Here’s the question…who do you think has made the most money for their respective record labels? This is not a popularity pole okay?

Streisand has always been with Columbia since the early 60’s and still records for the same label.
Elvis recorded for RCA for 2-3 decades.
The Beatles recorded their best music on Capitol then Apple
And Sinatra mostly Capitol and Reprise.
Considering sales, soundtracks etc… who do think made the most money for their record contracts? Others- of longevity I haven’t thought of?

Best answer:

Answer by Sweet Pea
Elvis? I’m not really sure
