Many stores and streaming services compress audio files to speed up downloads. Unfortunately, this can result in compressed audio sounding a bit different from the original tracks you uploaded to DistroKid.
As streaming services continue to adopt uncompressed, "lossless" streaming, this issue should become less common.
In the meanwhile, there's usually a way for listeners to make audio sound better from within streaming apps. For example, in the Spotify app (desktop or mobile), paid users can go into "Preferences" and turn on "High Quality Streaming."
