21:21 - Marcel Hubregtse Offspring? Did they cover it? Since Can't Get You Out Of MInd is a Kylie Minogue song. Or did you mean Can't Get My Head Around You?
21:16 - Unhealer That was my first riff as well. Then The Offspring's "Can't get you out of my head" then "Enter Sandman".
21:12 - Ceddybu well not the whole song, just maybe the intro and that nice riff that starts on the a and kind of ascends up. I don't know its hazy but songs like that are the first memories I have of learning actual songs on guitar
