is everyone just collectively pretending to like DJs but privately everyone feels too bad for them to tell them that actually the original songs were better
The traditional DJ is like a gallery curator: they play other people's music and let it speak for themselves. They enhance the music through context.
DJ-as-remixer (beyond mere structural changes) is an aberration (to a degree).
but it doesn't feel like an enhancement, it strips away the most important part of a song that makes it good - the melody - and replaces it with UNGH U UNGH U UNGH. there are SO MANY MEASURES without any change.
Yeah, if a mix modifies the original in such a way (removing the melody, adding beats), it's considered a Remix, which is the domain of Producers, not DJs.
By "structural changes" I was referring to a mostly-defunct 80s-era practice of restructuring-sans-destruction.
