67. Speedy Ortiz, "Tiger Tank"
These guitar kids from Western Massachusetts scored an excellent indie-rock debut, Major Arcana, with wry vignettes like "Tiger Tank." Sadie Dupuis breaks her twenty-something romantic angst down to its component parts, from "My mouth is a factory for every toxic part of speech I spew" to "My face is a label for how awfully I'm doing." But the guitars help her put it all together.
