yes, like kenisyes said, lyrics can sometimes be left lifeless without the music.
I tried posting lyrics to one of my songs on here as a poem, and Ukorin was able to immediately spot it.
I did some research and found that modern music depends on changing meter in the lyrics to keep it musically interesting, and modern lyrics depend on set musical meter to maintain structure.
If you notice the music is very very steady, then it is likely modern. If you notice the words don't follow a set meter, but have set ends for each line, they are likely modern lyrics.
