Apple still allows you to buy the album outright. Unlike streaming, a purchased AAC file is yours forever. The iTunes version often includes the rare Bill Conti score cues missing from other platforms.
Joe Esposito’s "You’re the Best" was not on the original 1984 LP. Due to licensing issues, it was famously left off. It later appeared on re-releases and his own album. If you find a download labeled "Original 1984 Album" containing that song, it is a fan edit.
