Nice thread. It would indeed help all people that come asking "which is the best software to...?"
A couple of suggestions:
Audio Player:
-foobar2000 (quite good, plays everything, plenty of features, very low resource consumer, not exactly a beauty contest winner)
Image Viewer:
-XnView (together with Irfanview one of my favourites. It has actually more features than Irfanview, but it's hard to leave the classic Irfan)
FTP Client:
-Filezilla (open source, full featured, easy to use)
CD/DVD Images Manager:
-Alcohol 120% (makes perfect images, burns to discs, includes virtual drive)
