Good ones!
There are a LOT of good ones that hadn't been mentioned.
"Save your Love" is an amazing song, too. I can't believe I forgot about that one. Others:
Yngwie Malmsteen - "Heaven Tonight"
House of Lords - "Remember My Name"
Helix - "Never Want to Lose You"
I also have another list, not power ballads but most underrated albums of my formative years (1980-1995):
1. Jefferson Starship - Winds of Change (1982) - amazing arrangements and vocals. Sounded modern and catchy without delving into the pop crapfest that Starship was soon to become. Some of Grace Slick's best vocal work since the early 70s, and the guitar work is good too. Even the banal Mickey Thomas sounded good here.
2. Bon Jovi - 7800 Fahrenheit (1985) - Bon Jovi's ONLY good album, really.
3. Skid Row - Slave to the Grind (1991) - also one of my top ten METAL albums, this also makes my top in all genres.
4. Concrete Blonde - Bloodletting (1990) - Just solid, good stuff. Have to listen to appreciate it.
5. Trixter - Trixter (1991) - just another "hair band" but they were every bit as good as anything else that was out then, but, they didn't come to the scene until 1991 and never hit it big.
