Melodi Brown music + What places can I upload it to?

I've made a few posts about this group on Reddit but I'll give a small summary here:

Melodi Brown was a 4-person girl group active from 2002-2003 in the UK. They were promoting their debut single titled "Naked" by performing it at certain places and playing a music video for it on The Box UK. They were meant to release a whole album (title unknown) later down the line but never exactly released the album or their original single with only promo copies of "Naked" appearing on eBay along with remixes of it on vinyls, along with an even rarer 5-track sampler CD with more of their songs on it. Eventually after they fully disbanded, some of their songs went to other artists like Rachel Stevens who got "Spin That Bottle", Tata Young who got "Never Knew My Baby", Jamelia who got "DJ" and most notably Britney Spears who got the song "Do Somethin'".

I have found a good amount of their music, varying in quality. Full list is:

- "Naked" (Single version in 320kb/s MP3 and album version in 128kb/s AAC / M4A)
- "Spin The Record" (Two different versions, the one from the sampler in 160kb/s MP3 and an earlier version leaked by a producer in 128kb/s MP3)
- "Never Knew My Baby" (127KB/s [] AAC / M4A)
- "Skin!" (127KB/s [] AAC / M4A and 128KB/s MP3)
- "Naked (Bloodshy & Avant Extended Remix)" (Low quality vinyl rip, grabbed from a YouTube upload)
- "Naked (Venus Tribe Remix feat. Familia)" (Low quality vinyl rip, grabbed from a YouTube upload)
- "Naked (Off-key Boot Remix feat. Familia)" (Low quality vinyl rip, grabbed from a YouTube upload)
- "Naked (Groove Chronicles Remix)" (Low quality vinyl rip, grabbed from a YouTube upload)
- "Naked (Nick Nice Remix)" (Low quality vinyl rip, grabbed from a YouTube upload)
- "Under The Pressure" (Demo supposedly meant for the group found by a Britney Spears fansite, 128KB/s MP3) 
- "10 Steps Back" (30 second long demo snippet, 128KB/s MP3, vocals by Kandi Burruss)
- "Don't Hate Me" (30 second long snippet, 128KB/s MP3, vocals by the group)
- "Naughty (Down By The Corner)" (30 second long demo snippet, 128KB/s MP3, vocals by Michelle Escoffery)
- "Tell Me" (30 second long demo snippet, 128KB/s MP3, vocals by Engelina Andrina)
- "That Woman" (30 second long demo snippet, 128KB/s MP3, vocals by Angela Hunte)
- "Touchdown" (30 second long snippet, 128KB/s MP3, vocals by the group)
- "Crazy Things" (30 second long demo snippet, 128KB/s MP3, vocals by Michelle Bell)

There's still songs from the group I'm trying to look for, those being:

- "Naked (Mark Picchiotti Vocal Mix)"
- "Naked (Mark Picchiotti Dub Mix)"
- "DJ"
- "Who's Fooling Who"
- "Do Somethin'"

The Mark Picchiotti remix of "Naked" is on vinyl and there's eBay listings for it right now but I can't get it unfortunately. Their version of "Do Somethin'" is also the most likely of the bottom 3 to surface but it probably still wont unless Angela Hunte leaks it (or someone else somehow gets it).

I also have the music video to Naked. Someone from the PopJustice forums named elektricblue found out it was on Screenocean. It has a watermark in the top corner but the rest of it is fine (I did replace the audio though, it was really low quality).

I already have the songs I found and the music video to "Naked" up on Soundcloud and YouTube ("Unreleased / Underrated R&B Grooves" already has the remixes up) but I wanna know if there's other places to upload them to. I know archive.org exists and I'm gonna try and get this on there after I'm done with this post but are there any other sites I can put it on?

Also sorry if this is kinda hard to read, not really good at making large posts on anything
