Final answer:
The music genre linked to Generation X is grunge, which emerged in the late 1980s and early 1990s and is characterized by its raw sound and emotional depth.
Step-by-step explanation:
The genre of music that is most commonly linked to Generation X is grunge. Generation X refers to the generation born after the baby boomers, typically defined as being born between the mid-1960s to early 1980s. Grunge music, which emerged in the late 1980s and early 1990s, encapsulated the spirit of Generation X with its raw sound, emotional depth, and sense of disillusionment with societal norms. This genre was characterized by its heavy guitar riffs, anguished lyrics, and flannel shirt aesthetic, and was most notably represented by bands such as Nirvana and Pearl Jam. Punk Rock did have an influence on grunge but is more directly associated with the late 1970s and early 1980s. Hip-Hop, while emerging around the same time, is more generally associated with an urban cultural movement rather than a generation-specific genre. Disco, on the other hand, was linked to the 1970s and is typically associated with the baby boomer generation.
