I disliked Amarok2 because I think the best part of this software is its editable playlist, where I can fix any tag I want, or order by it, or filter, etc.
And I think its interface is easier than keep creating different areas... I do prefer the big editable playlist and its powerful search field.
I can also read many useful information at the Context Panel.
So, when I installed a fresh Ubuntu 9.04, the first thing I did was remove Amarok2 and place Amarok1.4 back again, where it should ever stay.
