It is undeniable that both are great, but I find it really interesting when people love the same music that I do for completely different reasons! I love JNew first and foremost for the music--I discovered the lyrics a few months later and it would be the understatement of the century to say they were a pleasant surprise. If you had to chose one, which really does it for you--the music itself (chord progressions, melodies, rhythms, etc) or the poetry she produces along with it? Do you remember which it was the drew you to her music in the first place? Which are you more excited about hearing on the new album?
Also, do you usually sit down with a lyric sheet when you listen to it the first time? I realized the other day I didn't know all the words to 'Soft As Chalk'--a song that I have listened to many, many times.
