Yes I have same experience. Been using Last.fm for 14 years and that history can sometimes reveal things I didn't have any other chance to recall. My long youtube music favorites playlist is also interesting, because I usually add only things I really loved, and keep listening to it for a while, so there is just these time fragments, when I was kind of addicted to some of the songs, but against last.fm it just cannot compete at all.
EU doesn't want me to find a girl, how sad :/ still thinks this could be much more usable than what become of Tinder, especially when there is no filters, which when you live near border could be sometimes really bad. Not that I have something against other nations, it's just convenient to look only for locals.
