First of all, a song reaching #1 on the Modern Rock Charts means nothing more than Julian listened to "Ocean Breathes Salty" countless times while listening to HFS. Can you name every song that's hit number one on the Country or R&B or Hip-Hop charts? I doubt it.
Secondly, according to Wikipedia:
"Float On" - #1 Modern Rock Charts, #68 on U.S Hot 100
"Ocean Breathes Salty" - #6 Modern Rock Charts
"Dashboard" - #5 Modern Rock Charts, #61 on U.S. Hot 100
Seemingly, you're right; looks like "Dashboard" is a slightly larger hit than "Float On." Still, I guarantee you that, in a poll of 10 non-music geeks, they couldn't name a song other than "Float On," if that. And I'm not talking about people that are out of touch, either.

Also, to quelch this "one-hit wonder" business, if I recall correctly Ocean Breathes Salty went to #1 on the Modern Rock Charts, so that's 2 hits right there. Dashboard, I'm sure, has charted fairly well, also.
