And here is part 10. This part has albums not directly from the Sonic games, but rather remix/compilation albums related to both Sonic and SEGA.

UPDATE (21/02/2013):
As of today, these links will not be coming back. Since FileFolks never sorted out their payment system, I was never able to renew to a Premium Subscription. As a result my files were removed from their servers at a ate of several a day. I was going to upload the albums to RapidShare in due course, but thanks to a recent hard drive failure, I have lost ALL the albums I had ever uploaded. I cannot remember where I got most of these albums, and trying to obtain all 118 albums will be a nightmare.

So I'm afraid if you require your fix of Sonic the Hedgehog music, you will have to search elsewhere.

Major apologies to everyone who was hoping to download, but please place your blame on FileFolks and Seagate.

@BlueStreak: O_o you're missing QUITE A FEW albums, mostly little-known singles. Here they are:
1) DREAMS COME TRUE - The Swinging Star. This has an arrangement of Sonic 2's ending.
2) OFF-COURSE - Kotoba ni Dekinai. An old EP single featured in Sonic X.
3) T.I.C. Feat. Michelangelo - The Better One Wins. Released in Europe at some point, was probably a cross-promotion with the original Sonic game.
4) Wonderman. A single by Right Said Fred, used in the UK promotional campaign for Sonic 3...I have this one. Its a good song.
5) Sonic & Knuckles / Sonic the Hedgehog 3. An OFFICIAL REMIXING of Sonic 3 & Knux music. (By the way, you are ALSO missing an important Mega Drive rip: SONIC THE HEDGEHOG 3 & KNUCKLES.)
6) Westbam - Wizards of the Sonic. Sonic 2 tie-in single for Europe.
7) Sonic — They Call Me Sonic - CD Edition. The famous song's single, nuff said.
8) Sonic — King of the Ring. King of the Ring's single.
9) Sonic Team "PowerPlay" - Best Songs from Sonic Team. Best album featuring Super Sonic Racing and Open Your Heart; also the first known appearance of the Japanese Sonic CD themes. YOU GOTTA GET THIS.
10) Work it Out single. A remix with Dee Dee Brave. Hard to find.
11) CLUB SEGA 1 & 2. A pair of remix albums similar to Club Saturn.
12) Radio DC. Another remix album.
13) Sons of Angels - Thrill of the Feel. Crush 40's first album, BEFORE they were Crush 40. GET IT!!!!!!!
14) Sonic Adventure 2 BAttle Sampler CD. Nuff said, add it to Collection #8.
15) SONIC DRIVE. Sonic X Opening Theme single.
16) Mi-Ra-I. Sonic X Ending Theme 1 Single.
17) Hikaru Michi / Hiroshige Aya. Sonic X Ending Theme 2 Single.
18) T.O.P. / KP. Sonic X Ending Theme 3 Single.
19) Sonic X ~Original Sound Trax~.
20) TRIPOD BABY (SHADOW THE HEDGEHOG MIX). Dunno where to find this...but its a promo.
21) Summer of Sonic 2006 music. Get it at http://media.sonicstadium.org/. Since its fanmade stuff, it should be ok to DL.
22) Moshimo Yuki nara / DREAMS COME TRUE. Sonic 2006 theme single WITH REMIX OF SWEET SWEET SWEET.
23) True Blue & True Colors. SONIC's Best OF Albums. If you don't have these, WHAT ARE YOU WAITING FOR!?

Y'know what? This list is getting too long...PM or IM me.

Do you have a fix for the track "Title Music - Sonic & Knuckles" from Sonic the Hedgehog 10th Anniversary?

Another 1 to add to the list - 20 Years of Sonic Music.

It was only available with the collectors edition of of Sonic Generations. I can upload it if you like.

@KusanagiShiro - Sorry about the VERY late reply, but I didn't even realize you had posted here. Indeed.. I AM missing quite a few. And I do have Sonic 3 & Knuckles, sort of... but it's just each game in separate albums. Now that I've noticed your post, i shall try to get as many of those albums as I can.

@ggctuk2005 - Again.. sorry for the delay in replying... you may have forgotten by now. If you download the Sonic and Knuckles album, you can use the Title Screen music there, since they are both the same. However, if you wish, I can include the track in the 10th Anniversary album and re upload it.

@Kireirei - If you do have the 20 Years of Sonic Music album.. by all means, please do upload it.

Ok, will do :) I'll post the link here when it's done so you can add it to your list if that's ok?

I would be OK with that :). Thanks a lot BlueStreak for your uploads and thanks in advance Kireirei.

Many new albums have been added. See my first post for all the links ^

@Kireirei - Cool, that's perfectly fine. Let me know when you post the link and I'll add it.

@Ralbalboa - No worries, happy to do it :) Glad you're enjoying all the music :)

Here you go guys - all in mp3 format ripped from the CD ^.^

And you're welcome for all the new albums. Hehe... sorry for giving you more to download... lol :D I'm in the process of find as many albums as KusanagiShiro has mentioned... some were easy, most are not. As I get them, I'll add them to whatever Collection is the correct one.

And you're further welcome for the Sonic Underground music ;) They had some pretty catchy songs.
