How to Play Rocksmith Custom Songs (CDLC Guide)

Rocksmith Custom Songs: How the Community Kept the Ultimate Guitar Game Alive

For millions of guitarists, bassists, and music enthusiasts, Rocksmith wasn’t just a video game—it was an interactive, gamified revolution in music education. By plugging a real instrument directly into a PC or console, players could turn their favorite tracks into a rolling highway of notes, building real-world chops through the magic of video game mechanics.

While official DLC (Downloadable Content) releases from Ubisoft provided an enormous catalog of tracks over the years, the true beating heart of the game’s longevity lies elsewhere. Enter CDLC (Custom Downloadable Content)—better known to fans as Rocksmith custom songs.

Driven entirely by a passionate, talented community, custom songs transformed Rocksmith 2014 Remastered into a limitless sandbox capable of playing virtually any song ever recorded.

What Exactly Are Rocksmith Custom Songs?

Out of the box, Rocksmith supports songs purchased officially via the game’s store. However, the game engine reads standard package files (.psarc) for its songs. The community reverse-engineered this framework, allowing independent creators to chart their own tracks.

These custom charts—or CDLCs—include everything an official track features:

• The 3D Note Highway: Accurate charting for lead, rhythm, and bass arrangements.
• Dynamic Difficulty: Scaling notes up or down depending on your skill level.
• Riff Repeater Integration: The ability to slow down complex solos or loop difficult sections.
• Synchronized Audio and Tone: Custom-built amplifier tones mimicking the exact guitar sound of the original recording.

The Hub: CustomsForge and Ignition

The engine driving the entire custom song ecosystem is CustomsForge, a dedicated community hub. Its database, known as Ignition, hosts tens of thousands of custom songs ranging from obscure indie rock tracks and heavy metal deep cuts to classic jazz fusion and video game soundtracks.

Finding a song on CustomsForge is straightforward. Using Ignition’s search filters, users can look up tracks by:

• Artist, song title, or album
• Tuning (
