Since you singled out 1955 as a "bad" year musically, here's a list of albums from that year. The stuff the adults were listening to. I own 80% of the albums on this list, would purchase the remaining few before any R&R I can think of. But that's just me... Not a bad year for music at all, IMO.
In 1955, 1,615 albums and 4,542 pop singles were released in the US.
