Modify WordPress E-commerce Site

I need a WordPress e-commerce site for music downloads modified. The site is partially complete but needs adjustments to layout and functionality to improve user experience.

Requirements:
- User interactions:
- Preview tracks before purchase
- Add tracks/albums to a wishlist
- Customer reviews for albums and tracks
- Add prices for entire albums and individual tracks
- Upload images for all albums

Ideal Skills and Experience:
- Proficiency in WordPress
- Experience with e-commerce site development, specifically for digital downloads
- Strong design skills to improve layout and user experience
- Familiarity with customer interaction features (reviews, wishlists, previews)

Please ensure the layout is user-friendly and all functionalities work seamlessly.
