Nostalgia. In college I didn't have a LP player but I did own a couple of LP's. Santana's "Soul Sacrifice" was at the top of my play list, the album rapidly overplayed into pops and hisses (Jethro Tull and It's a Beautiful Day LP's close behind). Here is the title song from Santana's album as performed at Tanglewood in 1970. Excuse me now while I get up and dance away (well at least the old fart bob up and down).
