It depends on how big the songs are... apple products only hold low quality MP3's anyway so most of them are 2.5 to 6 Mb so That should give you and average of about 4000 songs but if your into rock or metal closer to 2000 but if your into pop then probably 4500 songs :)
The iPad can hold about 5,500 songs, assuming you have no apps, pictures, or videos. There is no exact number, as there are multiple bit rates per song so it can change. I have 4500 on my 32gb touch with about 2gb of memory left.
It depends how much Storage the iPad has, The iPad comes in 16GB, 32GB and 64GB Versions.
