#4 How many songs would you have if the average file size is 4,000 kb?
8 gb: 1,700 songs
16 gb: 6,000 songs
2 gb: 500 songs
160 gb: 30,000 songs
64 gb: 14,000 songs
1 Terabyte = 1024 gb: so im guessing 350,000 songs
This depends on the length of the song and the file format/type. A typical mp3 song of around 4 minutes averages 4 MB (4000 KB).
