I love Langston Hughes poesm... I don't know if they are cool but I like them (= Life is fine.-Langston Hughes. Dreams-Langston Hughes. Madam and her Madam-Langston Hughes. I, too sing America- Langston Hughes. Those are just some, I love his poetry and all poetry but yeah, those are some I can think of the top of my head.
I love the Lucy poems by William Wordsworth, my favorite being 'She dwelt among the untrodden ways'. I also like the poem 'Rising Five', and 'I know why the caged bird sings'- which is also one of my favorite books haha. I like Maya Angelou
I wouldn't define the poems I like as cool but most things written by John Keats are rather lovely and profound. I do enjoy them.
I love Edgar Allen Poe's poems, such as Annabelle Lee, The raven and The Tell - Tale Heart are some good ones. :)
I like Mihai Eminescu, George Bacovia and Nichita Stanescu [romanian poets]
