Our first Lunai Pack will be v150 because all the singers in it are trained on our core version 150. It will have 13 singers

2. Less weight. If you install each one individually, all our singers would weigh about 4gb. By downloading them all together, the weight is reduced to about 2.25gb. That's a reduction of almost 44%.
3. Simplify our work. This way it is easier for us to update the pack.
