Updated list and reasons
Overrated: Any hip hop (only like a few music of it), jazz vocals (no singing in jazz), Justin Bieber (AKA Crapber) (cannot stand how most girls at my school love him, it is annoying!! I agree with LOT8s, Mike, and Bryan) Taylor Swift (dull music and I hate country), Emienem, Any country, Any rock (ex. The Who), John Williams, Big Time Rush (bleh), Rihanna, and Kesha. It show how much I hate non TWC music even more.
Underrated: Any jazz (expect vocal)
Gulilty Pleasures: None. IDK what gulity pleasures means.
