Songs like Breaker, Fast as a Shark, Head Over Heels, Starlight, etc definitely do not suck.
Breaker (1981)
Breaker - 4/5 (speed metal, recognizable chorus)
Starlight - 3.5/5 (classic NWOBHM-style riffage, great solo)
Son of a Bitch - 3.5/5
Run if You Can - 3.5/5 (kind of thrashy mid-tempo riffage)
Breaking Up Again - 3/5 (ballad, bass 'ba dum-dum', more interesting melodies)
Feelings - 3/5 (mid-tempo galloping with a bit of Tank-swagger)
Burning - 2.5/5 (more rock n roll)
Can't Stand the Night - 2.5/5 (ballad, bass 'ba dum-dum')

Midnight Highway - 2/5 (reminds of 'You Shook Me All Night Long')
Restless & Wild (1982)
Fast As a Shark - 4.5/5
Ahead of the Pack - 4/5 (great progression/riff-play in chorus, lotsa swagger)
Neon Nights - 4/5 (descending acoustic intro, kind of an almost-ballad/hard rocking ballad, cool stuff going on in the leads)
Shake Your Heads - 3.5/5 (anthemic, especially the chorus)
Restless & Wild - 3.5/5
Flash Rockin' Man - 3.5/5 (Welcome to Hell/2MTM/etc)
Demon's Night - 3/5 (kind of thrashy riffage, some interesting bits)
Get Ready - 3/5 (getting into AC/DC territory, but still pretty decent)
Don't Go Stealing My Soul Away - 2.5/5 (cowbell, stop-start, but I like the melodic chorus)
Princess of the Dawn - 2/5 (love the acoustic pre-chorus but the rest is so damn repetitive)
Balls to the Wall (1983)
Head Over Heels - 4/5 (damn this is triumphant)
Guardian of the Night - 3.5/5 (feels Priestier than usual, I like the bridge a lot)
Fight it Back - 3.5/5 (faster)
London Leatherboys - 3.5/5 (like the strutting vibes and hi-hat)
Winterdreams - 3.5/5 (softest/most melodic song)
Losers and Winners - 3.5/5 (speed metal)
Turn Me On - 3/5 (also strong solo)
Love Child - 3/5 (average heavy/speed but great solo)
Losing More Than You've Ever Had - 3/5 (lmao @ those triggered toms 3 minutes in)
Balls to the Wall - 2.5/5
Metal Heart (1985)
Metal Heart - 3.5/5 (has a slight Holy Diver vibe, rather "melodic metal" overall, strong neoclassical solo)
Teach Us to Survive - 3.5/5 (kind of speedy bluesy stuff, James Bond-ish at times, I could see it having inspired 3D-era Wrathchild America, great fitting solos as well)
Wrong is Right - 3/5 (speed metal, sounds kind of familiar though especially in chorus (probably self-recycling), strong leads again)
Midnight Mover - 3/5 (stop-start radio rock/metal, total pop chorus)
Bound to Fail - 3/5 (big power metal-style outro, otherwise trad metal/hard rock)
Screaming for a Love-Bite - 2.5/5 (hair/pop/melodic metal, total cheese)
Living for Tonite - 2/5 (also generic rock/SFV-lite metal, but a great solo partially redeems things)
Up to the Limit - 1.5/5 (riffless bass-thumpy rock)
Too High to Get it Right - 1.5/5 (repetitve riffless rock, a bit Priest-y)
Dogs on Leads - 1/5 (more borrowed SFV-era Priest chord progressions, bass-thumpy but with stupid whispered/mumbled vocals, worst chorus so far)
