Art & Music Early Years and Y1 question...

I've just been asked to recommend software (Free or VERY low cost) for Art and Music in EYs & lower KS1...so I thought I'd share the list in the hope that others will add to it:
Big question...here goes!
More Musical Monsters - R-Y6 by Q&D ltd. (I really like this one, but there is a small price attached to it: http://www.q-and-d.co.uk/moremusicalmonsters1.htm
Black Cat Compose - linked to listening skills, good for differentiation and keeping kids focused: http://www.taglearning.com/search/publisher/by/BlackCat.html
Turtle Tunes - free game on the BBC website, a good starting point, but you can't save the file: http://www.bbc.co.uk/schools/digger/5_7entry/flash/createturtletune.shtml
Audacity: excellent composition software and its free! might be a little advance, but kids can quickly record anything (own voice singing or musical instrument) edit, and upload onto web side as a midi file: http://audacity.sourceforge.net/download/

Monkey Jam - fun and easy stop frame animation - used for storytelling too so strong links with literacy: http://www.giantscreamingrobotmonkeys.com/monkeyjam/download.html
TuxPaint: http://www.tuxpaint.org/ (probably the best I think)
Gimp - unfortunate name I know (I have used this with Key Stage 1 but can be used up to KS5, I also loaded this on to the Home Access laptops for looked after children at KS1 & 2 - (and it's free ;) http://www.gimp.org/
Drawing for children: Basic and fun - http://drawing.gamemaker.nl/
Rub-a-Dub - basic and free! http://www.brothersoft.com/rub-a-dub-7912.html
