Fathom for Web

Quick overview

Fathom is a browser-based music discovery tool focused on helping you uncover new artists that match your musical tastes, rather than serving as a place to replay familiar favorites. It combines artwork and track data from Last.fm with audio streams from Rdio. Many of the features work without payment, but a full Rdio subscription unlocks complete playback of tracks.

How discovery works

When you open Fathom you'll see a mostly empty canvas with a single search field. Searches are artist-based — you can't look up individual songs or specific albums. The app queries Rdio and places that artist’s most popular album in the center of the interface. Without a Rdio account you can preview short clips of tracks; Rdio subscribers can hear full songs. As an album plays, Fathom automatically finds and displays up to twenty similar albums; selecting any of those replaces the center album and triggers another round of recommendations.

Controls and interactive elements

The app offers several on-screen controls that appear when you hover over cover art. Main albums provide extended options while related items offer a smaller set.

• Share the current album to social networks like Twitter.
• Request more related artists from the active album.
• Pause the current track.
• Skip between tracks on the selected album.
• View the album and artist names at a glance.

For the albums listed as related, the quick actions are:

• Add the album to a playback queue.
• Dismiss the album from view.
• Start playing the album immediately.

On first use, Fathom will display instructional popups to explain navigation. Those hints reappear every time you leave and return to the site, which ensures new users don’t miss them.

Visual design and media sourcing

The user interface is intentionally minimal: soft white and gray gradients with clearly labeled areas for what’s playing, suggestions, queued tracks, and history. As you follow more recommendations, the grid of cover art tends to overlap those section labels, so the headings can get hidden behind album images.

All cover images are retrieved from Last.fm. Because the app depends on data from both Last.fm and Rdio, items need to exist on both services to behave correctly: if an album is only on Last.fm you’ll see artwork but won’t be able to play its tracks; if it’s only on Rdio the artwork may be missing and playback may not be available through Fathom.

Strengths and limitations

Positive aspects:

• Excellent for discovering artists related to ones you already like.
• Intuitive interface that’s easy to pick up.
• Stable performance even when many album covers are displayed.

Areas that could be improved:

• Full-track listening requires a paid Rdio account.
• There’s no volume control in the UI and audio defaults to a fairly loud level.
• Some layout decisions, like section headers becoming obscured by album art and recurring introductory popups, can feel awkward.

Bottom line

If your main goal is exploration rather than replaying familiar tracks, Fathom is a strong, straightforward option. It makes finding new, like-minded artists simple, and you can sample a wide range of music for free. Expect to need an Rdio subscription for uninterrupted full-track playback and be prepared for a few quirky design choices.
