suggested music varies wildly from my chosen taste.

When I start listening to suggested tracks, it starts out well, but eventually I end up in totally different territory, especially if I say that I 'like' something.

I want it to stick to my tastes as specified by the tracks I like.
There should be a way to craft by tastes, or remove tastes manually (like netflix) so you can repair or tweak your profile. Not just based on scrobbling...
