Need a program such as pure music with SB touch?

Any need for a program such as Channel D pure music or Amarra when using a squeezebox touch, or are these programs only useful when utilizing a Mac as a music server?
Also, the Logitech Media Server program is free. You can download it even without purchasing one of their players.
For anyone interested here is a very nice Android Marketplace application called Squeezeplayer that can be had for ~ $5 that will enable an Android tablet device to be used as a player device with Squeezeserver. No separate Squeeze player device needed.
