Not necessarily the greatest albums in the world, nor my complete and utter favourites, and indeed in many cases not ones I owned for myself, but these did have an impact on me at a personal level. A word of warning: there are more than 10:
"Sing The Blues" - The Simpsons. The first album I bought.

Also, my first introduction to that famous cartoon family.
"Bad" - Michael Jackson. It belonged to my big sister, but she played it to death. We all loved it and would take turns listening to it on my sister's Walkman.
"True Blue" - Madonna. Another of my big sister's albums, and it formed the soundtrack to a memorable summer in the south east of England.
"NOW 21" - various artists. We listened to a number of the earlier "Now That's What I Call Music" compilation pop albums, but number 21 was the one I played the most out of my cousin's hi-fi back in the day, and years later I tracked down a CD version for myself. Still one of the best, along with NOW 20.
"The Stone Roses" - The Stone Roses. Yet another one of my big sister's (much of my musical taste stems from her) and one that she would keep singing to us at every opportunity. I tracked down a re-release of the seminal album on its 10th anniversary in 1999, and it's one of my most played and favourite albums of all time.
"Automatic For The People" - R.E.M. It formed the soundtrack of the autumn of 1994, a particularly memorable and emotional time for me. I shall say no more at this point.
"Holst - The Planets" - Berliner Philharmoniker / Karajan. Classical music meant a lot to me as well as popular music, and still does. These days, classical music comes in various different recordings, albums and releases, and no one particular recording springs to mind when it comes to how they influenced me - for me, it's more the composition itself than the interpretation that holds greater influence. That said, this particular recording was one that my violin teacher once owned on CD, and months later I bought it on cassette and would play it on our car stereo. The sound of the car engine pretty much drowned out "Neptune: The Mystic" much to my annoyance.
"The Greatest Classical Album In The World... Ever!" - various artists. This particular classical music album, with its full works and excerpts of famous pieces, was one of our most played, and in fact was the first recording that we ever bought on CD.
"Everything Must Go" - Manic Street Preachers. One of my friends was really into the Manics in the mid-90s (at the start of their post-Richey, Britpop period) and wore T-shirts with their slogans all the time. It was still a great album with memorable tunes, and a Third Way for those bored of the Oasis vs Blur rivalry (me, I also liked Pulp

).
"You've Come A Long Way, Baby" - Fatboy Slim. The first dance album I bought, and a venture into the unknown for me. I was at Uni at the time, and I wanted to try out new music tastes. Still a favourite.
"Revolver" - The Beatles. My first proper introduction to the Fab Four, courtesy of a music student who played the album non-stop during a European trip. From there, there was no turning back.
"Vertigo" - Groove Armada. Another dip into the unknown, this formed the soundtrack of summer 1999, the most memorable summer of my life.
"The Facts Of Life" - Black Box Recorder. One of my personal favourites, it was pretty much a reminder of the close friendships I had developed at University, and the similar music tastes we had - we all owned this album. I occasionally play the whole album again from time to time.
"The Parker Tapes" - Cassetteboy. At times an early 21st Century relic and curio, it's still savage and a reminder of my subversive side amid all the political and newsworthy stuff going on in the world at the time.
"The Grey Album" - Danger Mouse. The point where mashup really started to get noticed, and perfect fuel for my Noughties obsession with mashup.
"Franz Ferdinand" - Franz Ferdinand. The first major album bought during my working life, and it brings up memories of finding my feet in the big world and deciding what sort of career path I wanted to take.
"LOVE" - The Beatles. The official Beatles mashup album, and one that evokes specific memories of owning my own house and trying to make a life for myself. Musically, it also opened up my appreciation of the Beatles back catalogue even further.
"Discovery" - Daft Punk. One of my favourite electronic music albums, and one of the best albums to listen to in the car. It served as a reminder of all those work commutes I would undertake, often to far away places.
"The Holy Bible" - Manic Street Preachers. I revisited this album not too long ago, at a time when I was starting to become disillusioned with the way things were going. Not a bright and cosy time, and perhaps the choice of music reflected that.
"A Boot Up The Eighties" - 10000 Spoons. One of my favourite mashup albums, and one where every song involved invokes a specific memory, character or person from my past and present.
"OK Computer" - Radiohead, and "Dark Side of the Moon" - Pink Floyd. I remember playing these two on a constant loop during a dark and troubling period in life just a few years ago. It served as the soundtrack for my wanting to throw everything away and start again. Which I duly did.
There will no doubt be more to come.
