You want an excellent 90s playlist? Listen to one made by someone who loves music and came of age in the 90s, who went through all the phases and tried on the styles of the decade. It was the age when metal gave birth to grunge; the sound that came to define the voice of a new generation.
This list is more the alternative hits, and less some of the lukewarm music of the 90s, that I personally, find rather boring. Grunge, rock, jangle pop, light punk, and some sounds that were fusions of these.
