you can view your songs while one is playing
go to the media player, click the music folder, press menu button, click play all, then when the first song is playing, hit the menu button and press the view playlist option.
your playlist appears in the black area and you can browse your songs while they're playing.
i found this very useful, don't know about you guys, but just in case, i decided to post it.
p.s. i now "know where the search button is" !!
