Answer:

1.152 GB if it will be at 128 kbps quality

Explanation:

So, let's say you choose your mp3 be 128 kbps (kilobits per second).

One byte is 8 bits. So 128 kbps = 16 kilobytes per second.

There is 60*60 seconds in one hour. So 16*60*60 = 57.6 megabytes per hour

Multiply by 20 hours to get your answer: 57.6*20 = 1152 MB = 1.152 GB.
