I listen to if they're on beat first
Then lyrics
Then the beat
If they're not on beat, I change the track.
If their lyricism is trash, regardless of the beat I don't really pay attention.
If the beat is crap but the lyrics are good, I'll still stay tuned, hoping the beat will grow on me.
I'll listen to just about anything that's on beat. But to get my props, wordplay is a must.
