Its success as a single can be attributed to its genre crossing qualities. I live in LA and its one of the only rap songs that gets played on KROQ, which is family known for rock music.

The opening riff is iconic. Solid lyrics and flow throughout. Would be curious to know what issues you have with it.

I've been a fan of Eminem since I was 12. I can say confidently that he has released a couple albums over the years where there probably wasn't a single song as good as Lose Yourself. So no way its one of his worst songs.
