I didn't like the last two at all at first, but now I love Master's Apprentices. The first riff goes on for a long time, but once you get into the riff and the rhythm and the lyrics it's really good. And the rest of the song is great too.
BTPISIO I like, but it's taken longer to get into. Most of the first riffs, I really like. And the "in the park" part. The ending is weird.. it sounds like someone stumbling one way, then the other way, then falling over.
