I just checked mine again as it’s a different day. They’ve changed as I thought they would.
Because I recently played 18 Months by Calvin Harris I get suggestions like Justin Bieber and Justin Timberlake. Two artists I have no intention of listening to, ever.
Out of the 30 there are 2 albums and 2 singles by Calvin Harris.
Another suggests I play The Rolling Stones because I recently played The Rolling Stones , should it not suggest something different
Two of the others are suggestions based on heavy metal albums I played recently. All the suggested albums in each are albums I play fairly heavily throughout each year and nothing new.
The last section says I played an electronic album recently, but I haven’t and suggests a fair amount of completely unknown stuff (which is good). 6 of the offerings are by the same artist. 3 are by the same artist it claims I listened to recently. An EP, and several compilations.
