i think the busta beats is dope, but those eminem beats had me playing relapse way more than i usually do eminem albums. eminem was really rhyming crazy on there but the accents and content was too much. the way he rhymed, connected verses and syllables was masterful. so in a way he wasted the beats- if he just rapped like he did maybe on the eminem show. i think that album would have got more respect. the production was excellent to me, it's aged well also. always gotta ask if dre really did it all though- i think he had his stamp on it but was actually putting it together is the question.
i hate questioning dre but it's legit. still the album beats are great and sonically crisp.
edit: rep for anyone who got the instrumentals to relapse, i been searching online can't find a good link for it.
