Part of the challenge of the album is it's nonsense lyrics and i am interested in 2 questions if people want to explore them. How is your enjoyment of an album based on
1) understanding it - explicitly lyrically
2) agreeing with it - does it confirm a worldview or challenge it
Foggy would care more about if it's dancable or not and that's valid also
Personally, I am a hypocrite so for Question 1 I will say that lyrics don't matter to me and I find that sometimes they get in the way. It's something I've said on the ambient albums I've nominated! That said, if you're going to put a 'message' out there then make it legible. It might sound common sense, but if Sinatra mumbled and launched 100 words a minute on his songs I doubt he'd have ever made it.
I don't care if the lyrics are immense such as Dylan, Joni Mitchell or if they are completely nuts like some of The Beatles and Zappa recordings. Lyrics suits the music and sometimes the music is more important than any message.
However, If I can't understand it, I'll miss your message so you will need to back it up with some top class melodies, beats and the rest. Rap albums suffer from the 'sameness' as well and you have to be either particular good, different or whatever to be able to hold my attention.
As for Question 2, I am ok listening to any type lyrics with any type of message. I can't honestly think of anything I would genuinely be offended by. Religious lyrics are interesting as it's not a common - to me anyway - theme, especially in rap. Or maybe just in the rap I've heard.
However, I am quite happy to sing Carols, Hymns and Peruvian Gloria's in a church because they are melodic. Hark The Herald Angels is wholly religious and a song I love and it's message and melody trump this. I think that's the important part!
In some ways, lyrics which don't say much probably put me off too. I find some of the lyrics in Coldplay and Oasis' (and plenty of others) songs so one-dimensional that they spoil the music. Some are like they've been written by a 12 year old boy writing his first love song.
I think Foggy has an excellent point about being danceable. Music should make you 'feel something' whether that's wanting to relax, move, think, contemplate, reflect, jump around or sing along then good music has this. There's a reason I can happily draw from music from Beethoven, Debussy, The Beatles, Zappa, Girls Aloud, Pantera, Michael Stearns, Run DMC... but not this album I'm afraid! :)
