It also reached number 15 on the U.S. Cash Box Top 100.

"Heart to Heart" was also very successful on the Adult Contemporary charts, reaching number three in the U.S. and number one in Canada.

The song speaks of the mutual opening of hearts as being the only way to preserve a relationship once the partners have allowed themselves to grow apart. The lyrics acknowledge the fact that most relationships do not endure the test of time, yet still some are able to do so. It features additional vocals by Michael McDonald, who co-wrote the song with Loggins.
