Highlights

Three tools. One app.

A downloader, a tag editor and a P2P file finder — no external programs to juggle.

Spotify downloader

Paste a track, album or playlist URL and NexusAudio grabs the audio via YouTube. No API key required.

Tag editor

Spreadsheet-style editing for MP3, FLAC, M4A and OGG with bulk rename, find & replace and cover art preview.

MusicBrainz lookup

Search releases, auto-match track titles and numbers, and embed cover art in all four formats.

Auto lyrics

Fetch lyrics from lyrics.ovh with a Genius fallback, saved straight into ID3, Vorbis or MP4 tags.

Soulseek P2P

A native SLSK client: search peers and download directly, with reconnection and queue handling.

15 themes

From Nexus Dark to Dracula, Nord, Catppuccin and Tokyo Night. Switch looks instantly.

Downloader

From Spotify to your library.

Your format, your quality, your folder — queued, tagged and lyrics-embedded.

  • Track, album or playlist — paste a Spotify URL and get the full track list.
  • No API key required — the built-in scraper works out of the box; optional keys speed up big playlists.
  • Formats & quality — MP3 (64–320 kbps), FLAC, M4A or OGG.
  • Age-restricted content — pass browser cookies from Firefox, Chrome, Edge, Brave or Safari.
  • Download queue — batch whole albums with progress bars and one-click cancel.
  • Auto-tagging — title, artist and album embedded on every download.
  • Spreadsheet editing — title, artist, album, genre, year and track number across every file at once.
  • Bulk rename — rename every file to “Artist – Title” in one click.
  • Find & replace — across tags, with regex and case toggles.
  • Extended tags — composer, album artist, disc, BPM, ISRC, publisher and more.
  • Cover art — download and embed front covers in MP3, FLAC, M4A or OGG.
  • All four formats — ID3v2, Vorbis Comments, MP4 tags and OGG.
Tag editor

Clean up your whole library.

Batch edits that take hours in other tools, done in minutes.

Soulseek P2P

The network for rare tracks.

Soulseek is where niche and hard-to-find music lives. NexusAudio speaks the protocol natively.

  • Native SLSK protocol — direct TCP implementation, no third-party client.
  • Search the network — results with user, size, bitrate and length.
  • Direct downloads — double-click a result to fetch it from the peer.
  • Reliable connections — auto-reconnect with exponential backoff and keepalive.
