That debut Third Eye Blind album is incredible. There are so many just excellent, infectious, and perfectly-crafted "alterna-pop" songs on that album.

In terms of your question, I can think of two 80s synth-pop/New Wave acts that are thought of as one hit wonders that actually have a bunch of great songs: Talk Talk (It's My Life) and A Flock of Seagulls (I Ran - So Far Away).
