Finding anime song listings with Anison database

Perfecting Google Translate’s results
Google Translate does an okay job of translating. I don’t like the diacritic symbols it uses (i.e. the long ō) instead of the romanji I’m used to (i.e. ou). To make sure Google translated a song title correctly copy and paste it back into Google search along with the anime name. Take MEGAZONE23’s ED Higeki no Idol for example, “higeki no idol megazone23.” If Google’s results say, “Did you mean” chances are Google Translate got it wrong. Of course, ANN is the easiest place to check ED and OP titles.
