In general, most if not all of the OSTs from: Yu-Gi-Oh! DM/GX/5D's, Naruto Shippūden, Dragon Ball Z/GT/Super & HunterxHunter.
In particular, these are the ones I can recall right now: YGO DM - Shuffle, Wild Drive & Warriors. GX - Precious Time, Glory Days. 5D's - Last Train. Naruto - Hero's Come Back!!, Blue Bird, Moshimo & Goodbye Memory. DB Z - Cha-La Head-Cha-La. GT - Dan Dan Kokoro Hikareteku. Super - Hello Hello Hello, Starring Star, Yoka Yoka Dance, Genkaitoppa X Survivor, Boogie Back & Haruka. HxH - Departure! & Hyōri Ittai.
Also, like Tormented mentioned, many divine/badass tunes that play when something is going down such as: DBZ Power-up/Transformation scenes & YGO themes of the god cards/Orichalcos seal etc.
(Remember that Latin music that plays on HxH, when Hisoka makes an appearance, anyone?)
