Some favorite 1993 singles....
"Too Much Information" by Duran Duran, a #45 Hot 100 single, and third release, from the album (Duran Duran, aka The Wedding Album) that produced the massive radio hits "Come Undone" and "Ordinary World". This should have received more airplay.
"What Made You Say That", the debut single by Shania Twain (yes, it was 30 years ago). It managed to get to #55 on the Billboard Country Singles chart. It wasn't a particularly remarkable song, but the video caught people's attention, especially the attention of Mutt Lange and the rest would soon be history (and historic, as Twain's Come On Over became the biggest selling album by a female ever, anywhere).
"Regret" by New Order peaked at #28 on the Hot 100, but hit #1 on the Alternative Airplay and Dance Club Songs charts. It was the first single from the album Republic.
"Possession" by Sarah McLachlan, a song that only peaked at #73 on the Hot 100, but was a huge alternative hit, reaching #4 on the Alternative Airplay chart and ended up being the 27th biggest song on that chart for 1993. The song was written by her in response to letters she got from stalkers and was even sued by one who claimed she used words from his letters without giving him credit. He died from suicide before the case was heard in the courts. Many people thought this was a love song, but a closer listen to the lyrics and knowing the background indicate that was very much not the case. The song was the first single released from her breakthrough album, Fumbling Towards Ecstasy.
"Will You Be There (In The Morning)" by Heart, a single from the album Desire Walks On, peaked at #39 on the Hot 100 and was Heart's last U.S. Hot 100 hit. The lead vocals were by the wonderful Nancy Wilson (who also had the lead on "These Dreams"). The song was written by the aforementioned Mutt Lange.
