I did the [at least semi-] pop star thing back in the 60s...three albums, toured, played Carnegie Hall, headlined as well as opened for a bunch of headliners, blah blah blah. Also did a lot of session work in the 70s, and in the 80s, had a string of successes with several new age albums...had some cuts on dance music compilations in the 90s. I consider it
freakishly lucky that I even got that far, because my musical tastes are not really mass market.
So, much of my career even when I was doing music revolved around music in some way. That includes doing music for multiple industrial, product, tutorial, and kiosk videos using Sonar, as well as two movies (not family friendly...but hey, my neighbors had this deadline, the original guy canceled, and the pay was great). So maybe I wouldn't be able to score "Lord of the Ring Modulators, Episode IV" with Sonar, but for everyday video work and YouTube releases, it does what I need.
IF you check out the YouTube channel in my sig, the music videos are nothing but Sonar + Vegas, and the videos were really done just to provide some visuals while the music was playing...I was able to put them together really fast.
Many of the musicians I know who use DAWs are into the direct-to-fan thing. I think they're making more bucks than I did selling a quarter million albums...
