In September of 1986, "True Blue", the title track off the album of the same name, became the third single. The retro 60s vibe of "True Blue" is irresistible- it's Madonna's wonderful tribute to the classic girl groups of that decade, and one of her creamiest pop classics. The song became a huge hit, peaking at #3 on the Billboard charts and yet another consecutive top ten hit. Though oddly left off The Immaculate Collection... oh well. It's perfect pop regardless.
