Personally, since the last few years, the duration something sticks around or gets re-playlisted has zoomed up, I used to generally get sick of things after 4 or 5 weeks, now 8 and 10 are not unusual and the longest-runners for the year have hit 16 or 17 top 40 weeks.

(admittedly part of this might be because I built a nifty excel to track them now and long runs are more aesthetic now)

For a while now, my charts have had a fast turnover. Single-week #1s are the norm, and anything over 3 weeks is particularly rare (mid-2023 was the last time a #1 single spent over 3 weeks at the top, thanks S Club). Anything that spends over 16 weeks or so in my chart is a huge hit, an average top 10 hit will spend 3-6 weeks in my top 40. Definitely speaks volumes of my attention span, but I also think this is an indicator of my taste growing over the years. Compared to when my chart began, I follow a much wider number of artists, and I know where to look to satisfy my urge for new music, so the turnover is naturally faster.

I think possibly I'm listening to a lower volume of new stuff (or replaying it)... I feel like a lot of my favourite artists' release cycles slowed down or their genre shifted compared to 6-10 years ago - covid is if course its own thing.
