sorry for the confusion, i re-phrase it.
1st point
I dont like the kd player (in my opinion it sucks, couldnt get playlist to work)

2nd
need an alternative i.e. walkman skin
the walkman phones (a.k.a the W-series of the sony ericsson) look cool, I want those ones. How can I get them and install it to the phone?

PS: the skins i want are for k-800
(checking this out now
240x320 Walkman 2.0 Skins - Top Sony Forums)

cant get any easier than that?
