gigs= gigabytes
I have 150 or so versions of #10, which amount to about 2 gigabytes. All others are fewer versions, and some very few... and a couple have none...yet. An average song is 4-10 or so kilobytes.... a few smaller, some larger. Thumb drives can be from 4 to 64 (or more) gigabytes. The entire collection would take 3-4 thumb drives unless one spent big money on high-capacity ones. I have a couple on 1 **terabyte** external drives for backup. That would take up quite a stack of CDs.
