The song Sugar, from the self titled album, was relatively popular at the time. Not as much as the Toxicity hits though. If I remember correctly, Chop Suey was the first major hit off Toxicity, but yeah, there were others. I think there was a title track, Aerials... that's all that's coming to mind. I think Aerials had the most commercial staying power, and I think it was also the last one released from the album.
