Heart was pretty much considered washed up when they released Heart in 1985.
They learned a few important things while they had taken a short sabbatical -- they knew that hooks were important and they knew they could play up their looks for MTV.
So, they delivered both with Heart, giving their audience anthemic hooks and tightly corseted bosoms, leading to the most popular album they ever had.
This doesn't mean it's the best, since its calculated mainstream bent may disarm some long-term fans, but it is true that they do this better than many of their peers, not just because they have good polished material from professional songwriters but because they can deliver this material professionally themselves.
Yes, "These Dreams," "Never," and "What About Love" don't quite fit into the classic Heart mode, but they are good mid-'80s mainstream material, delivered as flawlessly as possible.
There's still a lot of filler on this record, but the best moments are among the best mainstream AOR of its era.
