Planning - Development on Initial Idea for Artefact

I've decided to change a detail for my artefact since I believe it'll enhance the interest towards my target audience and the style for the product will influence the outcome of the entire marketing campaign.

The change I've applied to the project is towards the main idea. Rather than focusing a product on one particular major music artist; I've decided to do a collaboration of two artists in order to see if there would be an increase in the more likeliness of people willing to purchase the product if it featured two major artists.

I plan to carry out an video interview with customers within the targeted age group to see if they would purchase the product when it had the initial idea of only featuring one pop music artist or are they more likely to purchase the product now that it features two music artists.
