Bloopy said: On the right hand side here: http://playground.last.fm/demo/timeline?user=Kaltenhoenn&artist=Ulver #1 Ulver: Waltz of King Karl 2010-9-28 There is one problem with this feature for those who joined in the early days of Audioscrobbler.com and Last.fm. On the "Max" setting for my listening to Diana Krall, it says my first listen was on February 22, 2005 when in fact I had many scrobbles from before that date. I do not know whether this discrepancy is caused by the length of time of the "Max" setting or from the fact that there are no time stamps attached to scrobbles dated before February 13, 2005. I suspect the latter because it would be impossible to chart a scrobble on a timeline if the scrobble had no time stamp (the "Max" setting, in fact, may be set based on the introduction of time stamps).
However, this feature is great for artists first listened to since February, 2005, and for users who have joined since then.
EDIT: I went back and looked at my timeline for All artists and the earliest play is dated February 14, 2005. Almost a year's worth of scrobbles are not accounted for because they do not have a time stamp.
Date of the first scrobble
