Oh man, music. I'll proudly admit to liking old country. I absolutely adore Roger Miller, Marty Robins, and Johnny Horton. I don't even consider that a guilty pleasure. The real problem is some of the other stuff I listen to. Honestly, because most of my music comes through Pandora, I can't tell how popular it actually is, so I'm always surprised to hear music I like in public(Bulletproof by La Roux has been playing a lot lately!), and I usually don't talk about stuff besides what I consider safe artists.
For example, I really like Passenger, and I'm not sure most people would understand that beyond "Oh yeah, Let Her Go" which, in my opinion, was one of the worst songs on an absolutely fantastic album. I don't think it's a bad song. I just think pretty much everything else on All The Little Lights was better. I also think it's a funny title when the first Passenger song I heard was one about stalking a coworker. Also, one of his songs was used in Elementary. So maybe Passenger is mainstream, but I still would be really embarrassed to talk about his/their music (what's the right term for a band that's only one person?)
Which reminds me that I also really like Stalker Songs. I've been fascinated by them ever since I realized that they're a thing. And there are so many when you start listening for it. I get a little excited whenever I hear a love song and realize that the singer isn't really giving their partner a chance. There's one I've been hearing a lot lately, and it's kinda bad, but it has a couple lines that say "I've had to work much harder than this, for something I want, don't try to resist" and I just can't figure out how somebody would think that's romantic and not super creepy. I also enjoy them when they're intentional, like the Passenger song, Night Vision Binoculars, or Run For Your Life by the Beatles. Seriously, stalker songs are everywhere.
Man, I feel guilty just for all the namedropping I'm doing.
