I'm all mixed up with days and time zones...but I think I'm roughly on the right track now
But onto the question...since I didn't get into KT until pretty recently, there's not really any songs they've done in that time that are nostalgic already. However I have raked through lots of old video files and I'm quite familiar now with their chibi days, sometimes I even forget myself that I didn't even know who they were back then, lol. It feels like they've always been there and so for me some of the songs they sang in those days have a nostalgic feel for me. In particular I love Do~ Nika Naru Sa and Taiyo no Salsa, (I'm sure there must be others but I can't think of them right now), since they sang those songs a lot during their junior days but not so much recently, those songs feel really nostalgic to me...despite the fact I heard lots of other songs before those :S If that makes sense!
