Recommendations for software to use with Creative Zen MP3 player

[Chris G]

What do people panel recommend to use with a Creative Zen MP3 player.

Main requirement is to be able to download MP3s and put them onto the
Zen, it's not a requirement to be able to play them on the computer.

Podcast synchronisation would be a plus but lets try walking before we
run.  Doing this on windows has turned into a disatrous mess.
