Comparisons to hellogoodbye would also be appropriate; though the songs are written about (and probably during) high school, they don't really feel immature or inaccessible. Even a song like "My Attendance is Bad, My Intentions Are Good" overcomes the high school theme. Dan Hunter, the mind behind PlayRadioPlay!, is 18 years old with a talent far beyond his years.
The lyrics are fairly simple, but totally work for the genre ("emotronic" okay with everyone? Good). Definitely check this one out!
