aparently its can hold upto 20,000 songs but most I've heard of anyone having is like 7,500 and lots of videos and podcasts I only have 1,450 or so on mines and have like 63.5GB free lol
I filled up like 30 gb with music (roughly 6000 songs). then another 10gb with podcasts. and 20gb with movies (like 60). I also use about 5gb for pics, contacts, notes, and calanders.
totally depends if you have videos on it with out videos like 15000
a lot!
