I interpreted the question as more along the lines of "which tracks do you always wind up skipping over." There are very, very few of her tracks that I just can't listen to at all.
I guess I should clarify:
- Koufukuron (Etsuraku hen) - don't like the album version, do like it live. Not sure why.
- Togatta teguchi - like gekokujyo said, it's not bad, but it just seems kind of forgettable compared to the rest of the album.
- Rinne Highlight - this is kind of petty of me, but for some reason I'm really turned off by the fact that it's neither purely original nor explicitly a cover. Hearing recognizable elements from other songs is distracting. Except sometimes this can also awesome (e.g. Punk Mushi no Onna). I'm conflicted.
- Bouenkyou no Soto no Keshiki, 17, Shijou no Jinsei - I should really add these, based on the above reasoning.
- Aisaika no Choshoku - It *is* a good song, but it feels really out of place on Mayonaka wa Junketsu, and as a result I often would skip over it.
