Yes, I am seeing how many blog posts I can do over winter break. Why do you ask?
That title is probably going to mean the exact opposite of what you think.
At least what it would look like to me would be someone suddenly getting all preachy about how if you're ashamed of your musical tastes, you shouldn't be listening to that music in the first place. Which would be silly.
No, I'm going to get all preachy about the guilty, not the pleasure. See? Much less silly.
I subscribe to the rule of 'no guilty pleasure music', which I made up myself though I doubt I'm the first to think of it. Basically: if I like the song, I like the song. Any part of me that tries to tell me I should feel a certain way about music is antithetical to this. This is both true for the part of me that says I should like a song and the part that says I shouldn't. If everyone says I should like The Beatles, that still isn't why I like the Beatles. I like The Beatles because they made amazing music. I like Avril Lavigne's music whether she's being accused of X, Y, or Z, because I like her music.
In theory, I will spread this out to other facets of my life. It seems that I should at least keep this true for art forms--romance novels, tween-directed stuff, etc. And the point, by the way, is not to suddenly think that these things are the best ever*. It means recognizing that, regardless of critical acclaim or whatever else, liking them is no reason for guilt.
I am so not there yet, but you get the idea.
*I'm looking at you, Twilight-obsessed fangirl who sat next to me. I like the book; that doesn't make it the paramount achievement in literature.
