Tyrese -- Banned from the Airwaves in Delaware

You won't be hearing any Tyrese songs on the radio in Delaware in the near future ... because the singer's music has been banned from the biggest hip hop station in the state.

TMZ spoke with Tony Quartarone -- the station owner at KISS 101.7 -- who tells us he's not upset with Tyrese because he took a stand against liquor stores ... instead, he claims the problem was the way the singer addressed his listeners.

Quartarone says, "Tyrese was not kicked off the air for pointing out that liquor stores should not be located near schools ... I totally agree with that. But ... he proceeded to downgrade my audience by calling them 'homies.'"

Quartarone says he felt the language was condescending -- and that's why he asked Tyrese to leave the building Monday morning. After Tyrese tweeted about the incident, Quartarone says he decided to ban Ty's music until he gets an apology.
