What is the most common language used in Eurovision songs?

The most common language used in Eurovision songs is English. While songs can be performed in any language, English has become the de facto language of the competition, with the majority of songs being sung in English. This is likely due to the fact that English is widely spoken across Europe and many non-English speaking countries use English as a second language. Additionally, singing in English can increase a song's chances of success, as it may be more accessible to a wider audience.

It should be noted that Eurovision rules state that any language can be used, and many countries have chosen to perform in their national languages, showcasing their unique culture and identity.
