I guess having a lo-fi aesthetic is a pretty easy way to sound authentic/earnest, just like being interested in photography/liking Wes Anderson movies is a cheap way to sound plausibly interesting, but goddamit, Internet Forever sounds real.
The singer, Laura, does so in an accent, which I normally hate, but the sound is pretty effective here. Also, I really like bands that have the word "forever" in their name. It signals to me that this is a band that makes the kind of music that I've been using to innoculate myself against maturity since my adolescence. It's just cute shit guys.
