Metallica's first album Kill 'Em All has always been a mixed bag for me. It's pretty much the definition of thrash metal. It's got a dichotomy though, it's a pretty good album overall, but with that said, there are some songs on that album that I have a hard time listening to.
Metallica's Kill 'Em All (1983)
First, you have songs like Seek and Destroy, No Remorse, The Four Horseman, and Hit the Lights, which are just epic straight through head banging delight.
Seek and Destroy at Tushino Airfield.
(funny because bassist Jason Newsted sings the first part, very terribly)
And then you have some less-than-critically acclaimed songs, which just kind of rail on the guitar for a couple of minutes, claiming to be a song. Songs such as Metal Militia, Phantom Lord, Whiplash, Motorbreath, fall into this category -- the category of "we-are-trying-too-hard-to-be-like-a-more-badass-version-of-Motorhead."
Don't get me wrong, I can still listen to these songs, and I love Metallica, and Kill 'Em All, but you'll find me skipping them more often than not.
