We don't talk enough about SM's b-sides

Also I agree and disagree with this post.

Yes, SM b-sides are a GOLD MINE, but a lot of people praise them? When people praise groups like SNSD, EXO, f(x) and Red Velvet, etc. their golden discography is going to be mentioned, and especially their b-sides if anything (entire albums if you will).

they do have some great bsides indeed

I think it depends. Some songs are really good and others are so repetitive in an unpalatable way that is would be classified as an actual B-side, bonus, or unrelease track in the West.
