Even just reading the title puts this tune in my head. Absolute classic, I associate it with happy, carefree times when I've felt satisfied with myself.
it's my absolute favourite anime. I love the journey it takes you on from the start of the show to the end of the movie. I watch Endless Eight in a single sitting each re-watch (solidarity with Yuki ✊😤) and I cry during Kyon's triumphant speech in Disappearance each time
The dulcet tones of Tomokazu Sugita are now filling my ears
The Haruhi OST is one of my all time favorites--definitely check out the live orchestral arrangement Suzumiya Haruhi no Gensou if you haven't already (alternatively, the full concert Blu-ray including interludes is also up on YouTube). The solo violinist absolutely rips it on the fourth track.
for after you've listened to it
Put this under a spoiler because I don't want to prejudice anyone's experience of the music!
I'll be honest, the actual songs (as in the ones with singing) are the lowlights of the concert for me, which is why I always listen to a playlist which excludes them all. The trio are great as voice actors and fine as vocalists in a studio setting, but none of them have to training to be able to deliver a raw and powerful performance in a setting like this, so the energy really tanks during those sections (both because of the weak vocal performances and because the orchestra has to hold back). I understand why it was setup this way (fanservice, more or less), but as a purely musical endeavor I wish they had stuck to instrumental arrangements (classically trained soloists would have been another option, but I still think it would have limited the arrangement unfavorably).

I've actually only ever watched the english dub 
the first time I watched it was like that and that just became their voices to me lol. I just listened to his voice tho and I can see what you mean :>
also, thank you for the links! I'll check them out this weekend!
Lol, no worries--I prefer Sugita's performance which is a little more comedic/frazzled, but Crispin Freeman also did an excellent job! I happened to watch Haruhi as it aired, and since that was before the time of simuldubs I watched it subbed out of necessity, probably using CCCP when that was a thing, so it makes sense that I'd prefer the first version I heard, too.
...I just ended up watching like half of the first episode of Haruhi by accident, damn I love that show. I did a rewatch not too long ago but I might just have to do another--I've been doing more Japanese immersion lately so I could just watch it unsubbed for that purpose.

I realized that I never answered the question you posed! Let's see...well, I feel like insert songs are not really in the spirit of the question (God knows/Lost my music, Fuwa Fuwa Time, Ginga Ensen '05 (okay I know I said this isn't about insert songs but School Rumble has too many banger insert songs to count, just throwing that out there))
A couple from the original Pokémon anime that come to mind:
Shiawase no Sakura-namiki from Cardcaptor Sakura (Sakura dreamily rollerblading under the falling sakura petals)
