A record label has new records coming out
that need organising before their release to market
and therefore before any sales data is present

The sales data should then match up this when it eventually arrives

A user can create a tune
and list the tune writers and their CAE numbers
and add it and other new tunes to an album
and give the album a title
and give the tunes ISRC codes
and ISWC codes
and give the album a UPC
and upload the album artwork
