Answer: It depends.

Not all mp3's are created equal, depending on bitrate, song length & such, mp3s can vary in size quite a bit. Many mp3's are encoded at lower bitrates, 128 kb/s or lower. This results in reduced file sizes as well as reduced sound quality. 128 is fine for many people, but others dislike the sound quality and so they rip their cd's at higher bitrates, resulting in larger files.

I dont know where you get your mp3's so we cant tell exactly what your results will be, but if we make a couple assumptions we can do some ballpark math.

If we assume 128 kb/s bitrate, which is pretty average, you get about 1 minute of music per megabyte.

If we assume the average song is about 4 minutes, 4 minutes = 4 megabytes or so...

1 gb = 1024 megabytes = 256 'songs'

So 20 gb would give you around 5120 songs.... give or take.

Of course, if you wanted better sound quality, you might rip your cds at 256 kb/s, but then you would only be able to carry half as many songs.
