lol is it just me or did the get users top tracks/artists: long-term used to return the users top tracks/artist of all-time but now just from the past few years? 

(i feel like something must have changed because Waving Through a Window was my top all-time song for years up until a few weeks ago but now it isn't even in my top 100...)

I confirm that something has changed. I use to check my top track playlists, in two months I have 39 new entries in the long term one. In the last three years the list was pretty static until the first of January.Today I checked again and it was very different from what I used to see.

It would be nice to have a confirmation from Spotify.
