The music library for all those other tracks.
If you can't get it on streaming, or simply don't want to, Monolith is the desktop music app that lets you play all your favorites on every computer you have.

NO servers, hard drives, or syncing required
WHAT MONOLITH DOES
Go from scattered mess to unified music library.
Downloading or ripping tracks leaves you with files stuck on one computer. With Monolith, they all land in the same place, searchable, ready to play, and accessible from anywhere.
No need to view your recent purchases, hunt for old CDs, or scroll message history to re-find your favorites. They're simply in your library, ready to play, on every computer you have.
HOW IT WORKS
Centralize your music without spending a whole weekend.
Acquire the files, drop them in, and Monolith tags, uploads, and organizes your tracks. Your new additions are ready to play in seconds.
Drop your tracks into Monolith
Download, find, or rip whatever tracks you want to add, then drag the files or folders straight into Monolith. Whether it's a single track or a folder full of albums, Monolith will read them all.
Monolith reads your files and shows you what you have
Monolith pulls the tags and artwork already in your files and organizes everything by artist and album. Fix anything that's off, add what's missing, then hit accept.
Press play from any of your computers
Monolith processes your tracks in seconds. Install anywhere and the same library is right there, ready to play. No sync to worry about, no server to setup.
Repeat as necessary from any computer you want. Every track goes to your library and can be searched, tagged, and played from anywhere.
Your Library
Play, edit, and organize your library with ease.
Drag & drop playlists and play queue, global search, shuffle and repeat, volume that stays level between tracks, and more.
Build custom playlists
Build playlists for any occasion. Add tracks or entire albums at once, then drag and drop to reorder any way you want.
Search your whole library at once
Tracks, artists, albums, genres, playlists - everything can be found in an instant with global search.
Manage your play queue
Queue a new track, shuffle, repeat, or reorder the whole queue. You have complete control.
Organize by genres
Create custom genres to tag and organize your library. Tracks, albums, and artists can all be tagged with as many genres you like.
Toggle volume normalization
Built-in loudness normalization keeps quiet tracks and loud tracks at one steady level, so you don't have to reach for the volume when the queue advances.
Select from pre-prepared bitrates
Every track is automatically prepared at multiple qualities in addition to your original, so it plays cleanly on both a fast Wi-Fi connection and a weak signal.
Play whatever formats you have
FLAC, ALAC, MP3, AAC, Vorbis, and Opus all import and play. No need to convert what you have, just drop it in.
Keep your lossless quality files
If you bring any lossless formats (FLAC, ALAC, WAV), they never get downgraded. No lossy compression you didn't ask for.
Get one library on all your computers
The same library, nothing to sync by hand. Available on macOS, Windows, and Linux. iOS and Android coming soon.
Fidelity
Preserve the audio quality your tracks already have.
If you don't want to see your lossless formats downgraded, then you have nothing to worry about with Monolith.
Full Fidelity
Lossless in, lossless out
FLAC stays FLAC. No silent downgrade to 256k because it's cheaper to serve.
Every format
Your formats, kept as they are
FLAC, ALAC, MP3 - whatever you bring plays in its original format. Your originals never get converted.*
Bit-for-bit
The audio you upload is the audio you get back
Never re-encoded to a lower bitrate, never "matched", never replaced with someone else's master.
Other services match and replace based on fingerprinting, convert everything to one format, and re-encode lossless to lower bitrates. Monolith lets you play exactly what you uploaded.
*Except WAV, which we convert to FLAC to save on storage space and maintain the original audio quality.
Note from the team
Hello!
If you are reading this you most likely clicked on an ad from our latest Reddit campaign! Since we are marketing in music collection focused Reddit communities we wanted to put a little disclosure here about Monolith's metadata capabilities.
Monolith is in an early stage. Our team consists of just two people, and only one of us is a developer. There is still a lot of work to do in terms of metadata support.
If you are an avid music collector already and have files that you've added extra metadata to (think personal ratings, DJ software cue points, notes, classical music info, etc.), and that's important to you, Monolith will most likely not fit your needs right now, as it will strip most of this away and only keep the "basic" info like title, artists, album, cover art, and other things of this nature needed to organize your library.
At some point in the future we hope to expand our tagging capabilities. We know all that tagging is a lot of effort on your part and we would hate to dissapoint you, but we're simply not there yet.
If this doesn't apply to you and you just want a solution that let's you build a music library and play it, and you're happy with the features you've seen above, then we would like to welcome you to Monolith! We hope you enjoy using it and would love to hear what you have to say.
We have created a dedicated support portal and will be using it from now on to collect feedback, address issues, and discuss new features and plans. You can access it here. We hope to see you there!
Thanks,
The Monolith Team
