You Light Up My Life is the first solo album from singer Debby Boone. After the title track soared to No. 1 on the Billboard Hot 100, Boone needed to quickly assemble her first solo album. The result was a RIAA-certified platinum album (No. 6 Pop, No. 6 Country). Joe Brooks produced the album after writing and producing the title track.
Several tracks from Boone's album were previously recorded by Boone with her sisters as part of their work as the Boones. The album's closing track, "Hasta Mañana", written and recorded by ABBA, had charted earlier in 1977 for the Boones peaking at No. 32 AC. "When the Lovelight Starts Shining Through His Eyes" was released two years earlier in 1975 by the Boones reaching No. 25 AC. The track "Baby, I'm Yours" was released as the credited B-side of Boone's third single, "God Knows" (No. 74 Pop, No. 22 Country, No. 14 AC), from her second album, Midstream.
