Making a New Musical Home..

So, I moved to Spotify a couple of days ago, now that Rdio.com is dead.
I've been re-creating my play-lists, taking the time to delete some crud on the way.
More or less the music I used to listen to on Rdio.com (and Grooveshark before that) is there, so no biggies on that regard...
Two things raised a few concerns, tho, first, the Last.fm scrobbling (on the Spotify's web player, if that matters) is far from perfect... I've missed quite a bunch of plays while listening.
The other one is that somehow (and only on the T430's Firefox, maybe is related to the resolution?) the play-list look like shit; the same thing doesn't happen on the W530, go figure...
