In particular, I think the two albums Peter Frampton made for Atlantic Records in the 1980s (which are both out of print) are absolutely fantastic. My #1 favorite tracks from both these albums are both ballads. On Premonition (1986), it's "All Eyes On You", and on When All The Pieces Fit (1989), it's "Holding On To You". Other songs I like on these two albums are:

Moving A Mountain
Into View
Call Of The Wild
More Ways Than One
Back To The Start
Now And Again
