Music for toddlers - any ideas?

[KitKat26]

Hi, I know it is not quite the same as ipad/ kindle but my 2 year old LOVES his bedtime mobile which plays about 3 classical tunes with buttons he can press to change it/ switch on/off. I think it is time to progress forwards but does anyone know or have any ideas for a suitable music replacement. I saw a good website in the US called babyzoo.com but unfortunately they don't ship to the UK....
Any help very gratefully received!

There are some really nice songbooks available here I've just put all the CDs into my iTunes and play them for 2yo DS on my phone.
