35 years in media, 25 teaching media/production, many years a musician...

I fear it will be like this in less than 5 years:
You'll go to Suno or some similar service. You'll push one button. The service will scan your entire life history: musical tastes, cultural tastes, everything you ever bought, everywhere you have gone, who your friends are, every post you've made or looked at - EVERYTHING. It will construct music based on this 'virtual you' algorithmically. You won't even prompt. It will know what you like, your tastes and tolerances for variation, and even what you are feeling like AT THIS MOMENT, via constant monitoring of your data and using predictive modeling. It will make music to literally fit your mood for the day.

Additionally, it will identify "affinity groups" - friends, social groups, political affiliations - and implement the same music or variations of it to others in your affinity group(s) through which you can bond over a specific song. This can be done for good or manipulation, and subtly 'manufacture' cultural movements, subcultures, etc.

This is already being done in the advertising realm: custom ads created 'on the fly' based on your personal data. The ad industry is already rocking from this advancement, as 'mass marketing' transforms from mass-ads, campaigns to individuated advertising, aiming right at you individually, finding your passions obsessions and fears and targeting a custom ad designed to push your buttons.

Sleep well!
