Damn, you guyz are just hatin' on Terran because he's not here to defend himself. I don't know if I can pick a least favourite song. I'll have to think about it.
Oh man... I love Interlude 4 - especially when it's just the guitar and the bells and the pizz. bass and vcl. That has such a powerful atmosphere for me. I'd say it's one of my favorite motW moments.
I don't like Interlude 3 because when the strings come in, there are a lot of unresolved 9ths and 7ths in the melody over minor chords and that just happens to be a sound that irks me. I do like the congas though.
Also, I want to defend the Ferryman. I like Terran's intro (maybe it's because it's actually tonal and not just diatonic) and the way it leads into the rest of the song. I love the heavy, dissonant groove in 7 and Maria's vocals and Greg's wash of lead guitar.
