I've always liked jangly indie-pop, and I have often tried to create it, but I've always been too much of a monster to make nice, straightforward songs that people would actually, you know, like. I always have to find some way to ruin things.
The song linked above is by Spanish band Vacaciones. They make fine, fun, breezy indie-pop, and yup, we've got four chords strummed in sequence, head-bopping 4/4 time, but then they just randomly throw in one measure in 6! Wait, what just happened? Are things going to get weird? No, we head back to 4/4. OK, bopping head again.
Second verse, same as the first - wait, there's that measure in 6 again! And then back to 4/4 like nothing ever happened. The song jangles its effervescent and totally normal way to the end (less than two minutes long - I approve).
That weird little glitchy moment makes this unassuming song so so much better. That wait-did-I-just-hear-that moment. The reason why I find myself singing the rest of it.
I try to write a song like that and I end up with the following: an intro in 4. 4. 2. 7. 3. 3. 3. 4. 3. Because I am a monster.
