[(1) being my favourite (5) being my least favourite...]

• Dark Side of the Moon, Pink Floyd (1973)

• Frank, Amy Winehouse (2003)

NOTE: I seriously want to add a Beatles or Led Zeppelin album to this list but cannot pick just one album of either band that is better than the rest...so Zeppelin and The Beatles' ENTIRE DISCOGRAPHY are implicit! lol =P

BUT...if I had to pick ONE...

• With the Beatles, the Beatles (1963)
• Led Zeppelin II, Led Zeppelin (1969)
