Try to avoid picking pointless/banal/uninteresting songs. Go for the utter rock bottom.
1. 志方あきこ (Akiko Shikata)
Song: LOST CHILDREN
One of the scarce Akiko songs I almost never listen to. The reason is simple: it's bland, uninspired, and boring. And it reminds me of Nightwish's Amaranth.
2. Marissa Nadler
Song: Alabaster Queen
Least favorite song from the new album. It's not that bad, but a bit monotonous compared to the other tracks.
3. 三村京子 (Kyoko Mimura)
Song: 女子高生ブルース (Joshikousei Blues)
I only have one album of her and there's no track I really dislike. Maybe this song is the weakest, not as original/psychedelic/crazy as the rest...
Song: aphrodisiac (P.K.G. PHAT JAM MIX)
This remix is the only original track in the Aphrodisiac single, and it doesn't make it worth purchasing for the non-fans. Also it sounds very 90s, in both good and bad ways.
