Nope.
Many nopes.
Perhaps all of my nopes, in fact.
While I agreed with a lot of what you said Izzy, there was one point that stuck out like a saw thumb being lacerated by a bayonet held by a cackling sociopath in an otherwise bland and silent airport terminal: ‘Who gets to decide which song lyrics are poems and which aren’t?’
The reason I’m throwing all my nopes at this question is that it suggests that lyrics and poetry aren’t just different things (which they are) but that there is a relationship of importance, or even artistic validity, between them; essentially, your question implies that most lyrics are lyrics, but the best lyrics are poetry, which has all kinds of elitist cultural connotations I will now rage against, like soldiers gone to war and lost along the journey, against the dying of the light.
First up no art form is intrinsically ‘better’ than another; a crap poem isn’t better than an awesome rap because one is written by eighteenth-Century men with fluffy collars and greatcoats, and the other can be written by such strange creatures as ‘women’. And, by extension, there isn’t a progression from lyrics to poetry, where the best examples of the former can be accepted into the ranks of the latter like a graduate student being swept into doing a Master’s degree at the uni they just graduated from, and pulled across the ‘them-and-us’ divide between professors and students to torment new first-years with their own fiendishly incomprehensible lectures.
Also, this suggests that these forms of art are in some way exclusive, that poetry and lyrics can never cross over into each other’s forms of art, an idea I clunkily, although validaly, disproved at the end of the second stanza by mixing a Dylan Thomas refrain with a line from Canadian rapper Classified. This is my bigger concern with dividing things that are fundamentally similar – in this case forms of expression with words – into ‘lyrics’ and ‘poetry’, because they serve identical functions.
So sorry if that felt a bit ranty, I totally agree with basically the rest of your post Izzy – that one line just triggered the reactionary ‘no, lyrics are totally a valid form of art!’ bit of my brain that flares up whenever I hear anyone dismiss the artistic quality of Rise Against or a John Green novel.
