fairyland: "c/w"?

[ImpactBreaker]

Well the definiton of what is A Side or B-side is rather vague. By several observations I've made through artists discographies and the likes, I'd generally say A-side are main tracks, most likely to be featured in albums. B-sides are songs that are usually kinda like an alternative/bonus/random cover track and usually won't be featured on an album. There are obviously, several exceptions for these definitions and a lot of gray areas, which all depends how randomly artists and their companies will treat something like A or B. I believe this A and B stuff are reminescents from old vynils which had an A-side featuring the main songs and a B-side usually filler songs, bonus tracks, alternative songs and the likes.
