There is a reason why these songs were put as B-sides or unreleased. Mainly, they're unfinished. No unfinished song should replace ANY song on HTDAAB or ATYCLB etc. etc. It's like the Sweetest Thing... Sweetest Thing has NO business replacing any song on The Joshua Tree in it's b-side state. But it did have promise, so when it was redone for the Best of... THEN it becomes a good song, worthy of being placed up with the unfinished songs. But let's not go nuts here... Vertigo is a top 40 hit in America... it's been #1 on the Modern Rock charts... Native Song would not have done that. Could Native Son have been better if they had put more work in it? Maybe... but for some reason it just stalled and they couldn't take it anywhere else, thus how Vertigo spawned out of it.
