The Short Version
You cannot just paste a link to Spotify or YouTube into a Roblox game and expect it to work. Roblox has its own audio system, and music inside games is handled through Sound objects attached to parts, models, or the workspace itself. The files must be uploaded to Roblox as audio assets first, then referenced by their ID in your script or place in the Explorer window. There are two main paths depending on what you are trying to do. The first is for single audio clips like sound effects or short loops. The second is for background music that plays continuously across a scene. Most people confuse the two, which is why their music either doesn't play or cuts out after five seconds. Log into the Roblox website and go to Create, then Creator Dashboard. From there, navigate to Audio and click Upload Audio. Your file needs to meet Roblox's requirements: WAV, MP3, OGG, or AIFF format, and it must be under 20 MB per asset. Longer tracks tend to get rejected during review, so I usually split anything over four minutes into separate parts before uploading. The review process itself can take anywhere from a few hours to several days, and I have lost count of the times I submitted a track only to get it rejected for containing a brief snippet of a copyrighted song I did not realize was in the background noise. That happened to me with an ambient track that had a faint radio broadcast embedded in the mix. I re-exported the file using a spectral cleanup tool in Audacity, removed the offending frequencies, and resubmitted it roughly two hours later. The second upload went through without issue.
Once your audio is approved, open Roblox Studio and load your place. In the Explorer window, find the folder where you want the sound to live. For background music, the most common setup is to create a Sound object directly inside Lighting or ServerScriptService, set its SoundId to the numeric ID from your uploaded asset, adjust the Volume property to something reasonable like 0.5 or 0.6, and set Looped to true. If you put the Sound inside a Part instead, you also get spatial audio behavior, meaning the volume drops off as the player moves away from that part. That can be useful for regional music, but it is also the most common reason beginner developers accidentally create dead zones where the music suddenly goes silent. For triggered sounds like footsteps, door creaks, or UI clicks, place the Sound inside the relevant Part or Model and use a script or event to call Play on it. Do not rely on the PlaybackState property alone to manage this, because if multiple scripts try to control the same Sound simultaneously, you will get stuttering and overlapping instances that make the audio sound broken.
Playing Music Continuously With a Script
If your game requires more control than a simple Sound object can give you, like crossfading between tracks or stopping music when the player enters a certain area, you will need a server script. Here is a basic pattern I use: Create a Folder under ServerScriptService, put your Sound objects inside it, and reference them from a script. Use wait(0) or task.wait() to avoid scheduler overload. Set each Sound's AutoStop property to false if you want manual control over when playback ends. Call sound:Play() to start and sound:Stop() to end. When crossfading, overlap two tracks by starting the new one at a lower volume and ramping it up over one to two seconds while ramping the old one down. This takes about ten lines of code and works reliably across all platforms.

Common Pitfalls That Will Waste Your Time
Roblox audio does not support streaming from external URLs. Any attempt to set SoundId to a web URL will simply fail silently, and the sound will never play. Some tutorials online still recommend this method, probably because they were written before the current security restrictions were enforced. Do not follow those instructions. Another issue I run into regularly is latency between client and server audio. If you play a sound on the client and expect the server to sync it perfectly, you will get desync on slower connections. Always play server-authoritative audio on the server side for anything that other players need to hear in unison. Use RemoteEvents only when the trigger itself needs to come from the client, and then fire the actual sound playback from the server. There is also a hard cap on how many simultaneous audio sources a single player can hear clearly. After roughly eight concurrent sounds, Roblox starts aggressively damping the quieter ones, and the result sounds muddy. If your game has more than eight things making noise at once, you need to prioritize which sounds matter and merge or simplify the rest. A lot of developers do not realize this is happening until a player reports that the audio sounds wrong, and by then it is too late to debug without profiling.
What This Method Does Not Handle Well
Roblox audio is built for short-form gameplay use, not for full musical experiences. There is no built-in mixer, no automation curves for volume envelopes, and no way to schedule multiple tracks to fire at precise millisecond intervals. If your project requires a cinematic audio sequence or anything that resembles a proper DAW workflow, you are better off using a custom audio solution built on roblox's lower-level APIs or simplifying your design to work within the constraints of Sound objects and BasicScript control. It is not a limitation of effort, it is just what the platform allows. The process itself is not complicated once you understand where the files live and how the SoundId system works. Upload your audio, get it approved, drop a Sound object into your place, set the SoundId, and call Play. The places where it goes wrong are almost always in the edge cases around copyright filtering, client-server sync, and the simultaneous source limit. Plan for those three things and you will save yourself a day of debugging.
