How to unlock the Deponia Idol achievement in Chaos on Deponia - Definitive Guide
Second step: In the tavern - set the jukebox to the track number 4 then open it with the screwdriver. Go to the generator and use sugar bowl on it. Go back to the tavern and steal the notes from jukebox. Give it to the gondolier.
Third step: Go back to Bozo and tell him to go try again.
Fourth step: Go back to the tavern and repeat from the second step, except that this time you set track No. 3.
The gondolier have to sing all four tracks.
1. have bozo meet his woman for the first time, the Gondolier will sing a song
2. Shut down the power generator powering the tavern (use the sugar dispenser you get in the tavern on it), use the screwdriver on the jukebox and you'll see a sleeping man, take the sheet music he has on the stand in front of him, go outside and place the music on the Gondoliers stand.
3. go back to Bozo and ask him to try again. the Gondolier will sing a different song (but to the same rhythm)
4. go back to the tavern and change the song with the jukebox (the man will either swap the paper in front of him or pull up a new piece of paper), then go shut down the generator again and come back to the tavern, take the music that was replaced
Do steps 2 to 4 going through all of the songs in jukebox that the Gondolier hasn't played in front of the weapons shop
In Act II, the tavern jukebox has four music scores you can steal and give to the gondolier to sing. Ultimately, you only need him to sing "The Mating Song of the Junk Crabs". For this trophy, however, you need him to sing all four.
To steal one of the scores: pour sugar in the generator outside of the tavern. Enter the tavern and use the screwdriver on the jukebox flap. Pick up the sheet music (the default is "Dead Pigeon Tango"). Go back outside and place the sheet music on the gondolier's music stand.
To get him to sing the song: Go to the weapons shop and convince Bozo to talk to Bambina. During the cutscene of them talking/fighting, the gondolier will show up and start singing whatever song is on the sheet music in front of him.
Go back to the tavern and use the jukebox to change the music selection. Exit outside to the generator and start the process all over again.
I can confirm that 1) the time the gondolier needs to sing The Mating Song of the Junk Crabs for story-reasons counts for the trophy and 2) you can safely skip the cutscene of him singing.
