No, I'm not saying copies for personal use are unauthorized. Indeed, I also copy files from purchased CDs or vinyls for use in digital format (and before that it was cassette tapes, and, yikes! before that it was 8-track tapes for cruising with the tunes--turntables in the car just never worked very well).
VAX's info about 'fair use' is right on point.
In addition to copies of purchased music, I have downloaded copies of files not purchased, but certainly authorized by the artists, e.g., from the NEARfest website. I see these authorized downloads as their attempt to market their music. Sometimes I buy based on these samples, sometimes I don't. But I do not give any of these files to others or attempt to build any sort of commercial venture based on free sharing of others' work.
