A list of the 50 best hardcore albums of the 21st century has been published, although some outlets appear to be covering similar but distinct lists, such as the best rock and metal albums or albums with notable production quality. The existence of these various lists suggests a broader effort to catalog and evaluate notable albums of the 21st century across multiple genres. The specific focus and criteria of these lists are not entirely clear, with some outlets highlighting debut albums, post-punk, or hip-hop.
