I don't think there's anything that bogs down Bella Donna or TISL. I even love "Love Changes" and "That Made Me Stronger", which seem to get a lot of flack.
TWH has "I Will Run To You", which is a bit of a nothing-y song. It's perfectly pleasant and I don't think it's terrible. I'm kind of indifferent too it. I love "Gate & Garden" too.
RAL has "The Nightmare", which is a nightmare. I've replaced it with "Mirror Mirror" on my playlist.
OSOTM has "I Still Miss Someone". I agree that this is unnecessary. I also can't stand "Fire Burning".
SA has "Jane" and "Unconditional Love". I've never liked either. "Unconditional Love" came on shuffle the other day and I almost had to rip my own ears off just have to something to throw at the speakers.
IYD has "Cheaper Than Free". This song irritates me, because I love the music and guitar work on it, but the lyrics are just such utter tripe.
24KG? Well, let's not even go there
