Yeah, giving things seconds or third chances isn't work. You do it because you are curious. And sometimes things click, sometimes they don't....but it's never work. It's not punishment. It's not hard to do, if one is legitimately curious about a specific strain of music.
Wanting things just to immediately be appealing all the time, and just not bothering if they aren't, while obviously everyone's right to do, certainly doesn't give me much hope that they are really that interested in music much in the first place.
Expanding horizons is fun. It might be the only thing that even matters in art. Who would want to keep things safe? Zzzzzzzz
Am I now back on the subject of Get Up On It by Miles Davis?
You can imagine how many times it took me to get used to Kid A. It's a pretty common album not to get on the first go. It took me a while to get to its general experimentation. I'm now under the impression that it's their best album. It translates outside genres like IDM into a rock album very well by making sure the emotional tones of each song are not only consistent, but just as important as the actual focus of the album. I still find it just slightly too bold, like the first third or so of The Downward Spiral, but overall it helped teach me a lot about the importance of balancing diversity and consistency. As a result, I tend to gravitate towards more diverse albums in an effort to see if their diversity remains consistent.
Some very good examples of this type of album include:
Miles Davis - In a Silent Way (Jazz)
Beach Boys - Pet Sounds (Pop)
Nirvana - In Utero (Grunge)
Sonic Youth - Sister (Indie Rock)
Beatles - Sgt. Pepper's (Psych Pop)
Kendrick - To Pimp a Butterfly (Hip Hop)
Nine Inch Nails -nThe Downward Spiral (Industrial Rock)
Coil - The Ape of Naples (Electronic)
Pixies - Doolitle (Indie Rock again)
Tyler the Creator - Flower Boy (Hip Hop)
Swans - Children of God (Post-Punk)
Arcturus - The Sham Mirrors (Metal)
Minnie Riperton - Come to My Garden (Pop Soul)
The Clash - London Calling (Punk)
Dead Can Dance - Toward the Within (Darkwave)
Stevie Wonder - Innervisions and Songs in the Key of Life (Soul)
Fleet Foxes - Fleet Foxes (Folk)
Death Grips - Exmilitary (Experimental Hip Hop)
Love - Forever Changes (Psychedelia)
Low - Hey What (Experimental)
Hell - Hell II (Drone Metal)
Boris - Feedbacker (Drone Metal again)
Blood Brothers - Crimes (Post-Hardcore)
The general idea of creativity is to see how much you can do with the genre you play. In many cases, the best choice is to include influences from other genres like many of the albums I listed do, but there's also the risk of that backfiring. When following an absolute vein of consistency by linking emotion through one sound and then with another sound that previously explored a different emotion, like the switch between maniacal anger and teenage moaning we get on In Utero, one can also use a specific kind of production, like Albini's famous noise rock style, to cover grounds that grunge is already known for, including the poppy alternative, the noise punk and the Melvin's sludge.
While albums that follow a single genre can also risk being monotonous, occasionally we get something that takes that one genre and boasts an enormous level of creativity without going into other genres, like Michael Chapman's Fully Qualified Survivor, Leonard Cohen's debut, or the screamo album Document 8 by Pg. 99. And even if you could also tag that last one as a second genre: emoviolence, both genres are largely present on each song, so that hardly matters as the overall genre goal of each song is the same. Those 20 minutes showcase a range of everything emoviolence is capable of without help from other areas.
Obviously, diversity isn't the only thing that matters. Songwriting quality is an absolute must when making a perfect album. Certain songs may not even be in the same league as the rest. The four best personal examples I can muster are Tame from Doolittle, Rape Me from In Utero, Piggy from The Downward Spiral (too long at the end), and especially The prophet's Song from A Night at the Opera. Not every album has to be amazing, but it helps if you have quite a few amazing songs to balance out the same number of great-although-not-amazing songs. A fine example of that would be Children of God by Swans, where songwriting quality can vary a little depending on where the repetition is applied in each hypnotic song.
