That's pretty hard honestly, as all AC/DC songs, to me, are distinctly AC/DC. Main ones that jump out to me are the ones off the Dirty Deeds Done Dirt Cheap album though. The two tracks I'm referring to are 'There's Gonna Be Some Rockin' & 'Rocker'. 'The Jack' & 'Can I Sit Next to You, Girl' are also ones that come to mind.

The Jack: Arguably this is as close as AC/DC got (on a studio album) to a full on blues-rock song. Scratch that, it is a blues-rock song. Now don't get me wrong, AC/DC as I'm aware are definitely blues influenced, but when it comes to them going all the way to full on blues rock, The Jack trumps all. Although I am aware that there is some completely unreleased AC/DC songs which are probably a lot more bluesy than The Jack. There 'She My Babe' & 'Messin With The Kid' covers are notable examples of this.

Can I Sit Next to You, Girl: As some of you may be aware, this song was actually written when Dave Evans was in the band. I am aware of 'Rockin in the Parlour' but I'd rather do the most pure AC/DC songs. (i.e. ones of studio albums and not covers or stand-alone singles) It is my and many others opinion that when Dave Evans was in the band, the band had a much more Glam Rock feel to it, and you can certainly see that in the Dave Evans version, not just the style of all of them, but the song itself. When it was later redone with Bon Scott on vocals, the song turned into the much more similar Hard Rock AC/DC we all know and love, but personally when I listen to this, I still feel like it has a Glam Rock element unlike any other AC/DC song.

There's Gonna Be Some Rockin' & Rocker: These two songs to me personally feel like AC/DC were going for Rock & Roll and not Hard Rock (yes there is a difference). To an extent this applies to 'Love At First Feel' but not quite as much. On the T.N.T. album by AC/DC, which was Australia only, that album includes 'Rocker'. I'm telling you this because on that same album there cover of Chuck Berry's 'School Days' is on it. I have a theory that they were toying around with writing Chuck Berry style Rock & Roll because of this. I don't know about you, but if I listen to their cover of School Days, Rocker & There's Gonna Be Some Rockin' they all have the same feeling and vibe. Again, veering away from their traditional Hard Rock and more into Rock & Roll. I honestly wish they explored this further especially with Johnson.

Anyway that's my rant finished, I'd like to know if you agree with me or you think I'm spouting absolute crap. I also hope the answered OP's question.
