Karaoke Iko! Episode 2 Discussion

I like this series a lot.
It portrays very well the feeling of fearing that you got involved with something potentially very dangerous.
Also, I think the songs they were singing are real songs.
I recognise "Charles" produced by Kitani Tatsuya and sung by Ado (or in this case by background character yakuza member #2)
Reply / mention me if you recognised anything else, I am curious if they are all real songs.

@gorkthe134th Isn't there a list of songs in the credits at the end? I've seen something listed with various years, but I can't read japanese, but real songs do need to be credited.

Thanks @Mimi_Violet!
I confirmed that the first few match (as best as the characters could make it match).
Having a Kataka gojūon open helps a lot when researching that stuff.
Also, small correction: Charles (シャルル) is originally sung by flower, but I got confused because Ado's version doesn't have the "歌いました" part she usually adds to the titles of her covers, plus it's not in her "歌いました" playlist.
I'm not sure what's up with that; maybe it's a new version they made, but I don't know the original well enough to tell.
