does DD want just music or music & video?
ipod shuffles hold about 250 songs, a little bigger than a postage stamp...comes in all sorts of colors (yellow too--she wanted yellow, right?)
around 40-50 dollars, I think
Walmart has the best price on those
Nano comes in 8g & 16g (3rd & 4th generation)---3rd is the older model & a little more square in shape, 4th generation is the newest model & more rectangle shaped.
8 GB capacity for 2,000 songs, 7,000 photos, or 8 hours of video $135
16 GB capacity for 4,000 songs, 14,000 photos, or 16 hours of video $180
the Nano prices are best on
Amazon & usually no shipping or tax.

both come in a rainbow of colors
