I couldn’t find any suitable thread to put generic feedback into, so i took the liberty…
I don’t see the USP of these, compared to bookmarked focus criteria, but there’s a couple of threads for that already.
I tried the feature out by generating a big playlist of tracks from the genre Pop/Rock and limiting them to 21st century material.
Thing is, i get a lot of material in those lists that seem utterly wrong. A Miles Davis live recording from 1970, but released in 2003? I admit that it is basically not wrong per se, as it was one of his fusion tinged work, so could possibly be labeled Rock, but still… Not what i was looking for.
This was but one example, but many more surfaced.
This also caused my server to burn calories, a lot. I ended up deleting it but it took quite some time for the Core to settle again.
So, time span needs to take recording date into consideration, and genres really need to look at weighting the genres for better targeting.
