Well up to 500,000:) If it's a Barbie Girl Mp3 then about 240 songs,but of an ipad ipod or iphone any thing Apple made then about the above 500,000!!! Thanks for veiwing.
a 4gb mp3 player can hold about 13oo songs but it matters how long each song is or if you have other downloaded things on there like if you have a movie you will get less room for songs ..
It varies depending on the size of the songs that you put on your MP3 (most songs are between 3-4 MB), but on average, you could probably fit about 2500 songs, give or take.
