Comment Curation by record label (Score 1) 183
Nothing prevents other people (those not stupid enough to sign away all their copyrights to a record label) from placing their musical creations in the public domain
Other than that FM radio won't play your music unless you're "stupid enough to sign away all [your] copyrights to a record label", and not all of your listeners have hundreds of dollars per year for a data plan to listen to Internet radio on the commute. Labels do at least some level of curation and promotion, a service on which mainstream DJs rely.
