This song by Lassie Foundation called El Rey, I heard it once before but just recently as I re-watching Buffy the Vampire Slayer episodes, The Prom episode is Season 3 had this song on.
It represents how to describe something you love but cant describe it, you want to grasp it and hold onto that memory forever. Kinda of like me and summer. This mellow tune is great for a relaxing time and to reminisce about the 90s, which this song is from. 1998.
Classic 90s vibe that leaves you breathless.
