Purchasing additional songs for Guitar Hero on the Wii console expands the game’s music library, allowing players to enjoy a wider variety of tracks. These songs can be acquired through the in-game Music Store or by using Wii Points purchased from the Wii Shop Channel.
Expanding the song library enhances the overall gameplay experience by introducing new musical genres, iconic hits, and challenging charts. It allows players to customize their setlists and tailor the game to their musical preferences. Additionally, purchasing songs supports the game’s developers and encourages the creation of future content.
