Generally speaking, a song is about 4mb of data though some songs can be much less or almost twice as much. Therefore, any estimate of how many songs 8gb holds is a general estimate. One gigabyte (GB) holds 1,024 MB of data of any form. This is a standard measure that does not change with the type of files being stored. Since one GB is 1,024 MB, eight GB is 8,192 MB.
