In two words you can sum up how many songs the iPod 160 GB holds. Those words are “A LOT”. Basically though, it depends on what else you store and how long the songs are and a few other variables. For example, you could get about 40,000 songs on the iPod 160 GB, 200 hours of video and 25,000 photos. However if you didn’t have as many photos or hours of videos you could get a lot more songs to fit on this iPod model, or fewer if you have more hours or video or more photo. Either way you stack it up though, you have enough storage to fit a great deal of songs, videos and photos on an iPod 16 GB.
