I have lots of favorite 90's song that I still regularly sing in the karaoke whenever my friends and I go out. On top of our list is Iris by Goo Goo Dolls. We'd play it non-stop until everyone gets the chance to sing it solo. I also remember a friend being obsessed with the song Closing Time. I didn't know the song by then but he made me appreciate it; hence, that, too, became one of our constant songs. And of course, Backstreet Boys songs will be forever favorites (I Want it That Way, As Long as You Love Me, Quit Playing Games, Show me the Meaning of Being Lonely, No One Else Comes Close, and Lay Down Beside Me).
