Ok it's taken me forever to post this and to be honest I've been too lazy to write a review for my number one.  So, I'll go w/what the All Music Guide has to say about it. 

Here it is...

Number 1 - Blur - Parklife

Modern Life Is Rubbish established Blur as the heir to the archly British pop of the Kinks, the Small Faces, and the Jam, but its follow-up, Parklife, revealed the depth of that transformation. Relying more heavily on Ray Davies' seriocomic social commentary, as well as new wave, Parklife runs through the entire history of post-British Invasion Britpop in the course of 16 songs, touching on psychedelia, synth pop, disco, punk, and music hall along the way. Damon Albarn intended these songs to form a sketch of British life in the mid-'90s, and it's startling how close he came to his goal; not only did the bouncy, disco-fied "Girls & Boys" and singalong chant "Parklife" become anthems in the U.K., but they inaugurated a new era of Britpop and lad culture, where British youth celebrated their country and traditions. The legions of jangly, melodic bands that followed in the wake of Parklife revealed how much more complex Blur's vision was. Not only was their music precisely detailed — sound effects and brilliant guitar lines pop up all over the record — but the melodies elegantly interweaved with the chords, as in the graceful, heartbreaking "Badhead." Surprisingly, Albarn, for all of his cold, dispassionate wit, demonstrates compassion that gives these songs three dimensions, as on the pathos-laden "End of a Century," the melancholy Walker Brothers tribute "To the End," and the swirling, epic closer, "This Is a Low." For all of its celebration of tradition, Parklife is a thoroughly modern record in that it bends genres and is self-referential (the mod anthem of the title track is voiced by none other than Phil Daniels, the star of Quadrophenia). And, by tying the past and the present together, Blur articulated the mid-'90s zeitgeist and produced an epoch-defining record.

I will add that this was the soundtrack to my first trip to the UK in 1994.  That trip opened my eyes to the world outside of the US and this was the record (and Definitely Maybe) that I listened to on trains as I went up and down Britain for three months.  To this day I could listen to this record over and over and over and not get sick of it.  I know every word, every riff, every drum beat, everything and if you want I can sing it to you.   1994 was probably the most important year in my life, it was nothing but good times, amazing people, and brilliant memories.  For those reasons that year and this record will always be my favorite.
