Free or not $$$
 

Does billboard musical archives vault information free as far as albums and singles go in popular music for music from the 50s/60s, ect… or should one subscribe to get such info? How can one find out what albums/singles were released in any given year by popular music artists then... free info or pay for it to receive it in an orderly fashion/manner?

google the deep web go past like page 5 :P
