For starters, I guess I want to see some receipts about the album "being a party" or whatever - I'll totally accept that as an interpretation, but is that a concrete fact? Either way that doesn't make it particularly good, or interesting, or suddenly make me think that it's not way too long and samey. All art has a theme, that in and of itself doesn't make an album better or worse.
When I say it feels like a playlist, I mean that it doesn't really feel like it has any sort of rhyme or reason to its track layout and overall tone/mood. It feels like a singles collection. There are some great singles on here! But as an album listening experience, it really hasn't clicked with me yet - which is a bummer, because Demon Days and Plastic Beach really work for me as full album experiences. I don't really care one way or the other if it's "supposed" to sound that way.
