My discography contains classical music, jazz, rock, fusion, k-pop, oriental, french songs, old french singers, pop, commercial crap, electro, drum'n'bass, trip-hop, shibuya-kei, rock fm etc... so yeah, I could be very embarrassed when at the moment I explain how I like "St Matthew Passion" by Herreweghe the person handles Speed 1st album with me instantly saying "Handle with care, it's the first press"... but no, I'm not.
There's no embarrassing songs, just people who'd like you to be embarrassed.
(besides of that, there's this dvd concert of Britney Spears I'm really ashamed of... ahahaha )
