The tapped, syncopated intro to Van Halen's "Mean Street", along with the main riff following it.
The intro to Van Halen's "I'm the One".
The slowly building intro to AC/DC's "Snowballed" through when the bass and drums kick in. That whole song is highly underrated.
Intro for Whitesnake's "Still of the Night".
The beautiful, melodic solo in White Lion's "When the Children Cry".
The following section of the song "Mother Love" by Queen...
I've walked too long in this lonely lane
I've had enough of this same old game
I'm a man of the world and they say that I'm strong
But my heart is heavy and my hope is gone
Out in the city, in the cold world outside
I don't want pity, just safe place to hide
Mama please, let me back inside
The sound of the baby crying at the end of the above-mentioned song also always gets to me...
The end solo in Boston's "Hitch a Ride".
Neal's solo in "Still They Ride", etc., etc.
