Azerbaijan's participation in Eurovision has always been irritating because:
1). Azerbaijan have been busted for cheating in Eurovision by offering bribes. In fact Eurovision had to change their rules because of Azerbaijan's shady bribery tactics (and stop Azerbaijan from trying to cheat again).
Here's an undercover documentary from the BBC (from the UK) called "Eurovision's Dirty Secret Azerbaijan"

2). If someone in Azerbaijan votes for Azerbaijan's neighbouring country Armenia, the police have tracked those people down, dragged them to a police station, and questioned those people for why they voted for the "enemy" (and have also tried to arrest them).
Azerbaijan television have also in the past blocked Armenia's entry in Eurovision airing on Azeri television (they literally block the video & sound when it's Armenia's turn to perform).
For the police to get involved and drag people to police stations for simply voting for a song, and for the television bosses to shut down the television signal when a country they don't like is performing....what the fuck is this country thinking, are they another Iran or Saudi Arabia?
3). Azerbaijan pays a shitload of money to have non-Azeri's from around the world - put together Azerbaijan's Eurovision entry. The song-writer, song producer, song composer, music video producer, dancers on stage, etc....are 99% of the time foreigners and not Azeri's - and I don't think that's what Eurovision is about.
Since Azerbaijan's entry in Eurovision, just 1 song was actually written and composed by an Azeri. Every other song, Azerbaijan have had to pay other people from other countries (mostly always Sweden) to write and compose Azerbaijan's Eurovision entry.
It's terrible because it makes Azerbaijan look like an uncreative joke (that they cannot write and compose their own songs)....and quite frankly a country habitually year after year after year having to rely on another country to basically create their entire Eurovision entry for them - is in my opinion not really in the spirit of what Eurovision is supposed to be about.
