Metadata variants are attached with documents of different file formats. MP3 files commonly contain ID3 metadata tags. This article discusses how to read different MP3 tags in Java. One by one, we will see how to extract ID3 (IDEv1, ID3v2), Lyrics, and APEv2 metadata tags from the mp3 files using Java Metadata API.
The following topics are covered below:
- Java API to Manage MP3 tags
- Read MP3 ID3 Tags – ID3v1 & ID3v2
- Get MP3 Lyrics Tags
- Retrieve MP3 APEv2 Tags
Java API for MP3 Metadata Tags
GroupDocs.Metadata is equipped with APIs to automate metadata management of various file formats within applications. It’s Java API allows you to read, update, add, clean, and remove the metadata for many file formats within the Java application. We will use it to work with MP3 metadata tags.
Download and Configure
Get the metadata library from the downloads section. For your Maven-based Java application, just add the following pom.xml configuration. After this, you can try the examples of this article as well the many more example available on GitHub. For the details, you may visit the API Reference.

The following steps show how to read the MP3 ID3v1 tags using Java.
- Load the MP3 file using Metadata class.
- Retrieve the MP3RootPackage using the getRootPackageGeneric() method.
- From the root package, retrieve each of the ID3v1 properties.
The following Java source code reads some of the MP3 ID3v1 tags of the MP3 file.
You can extract the ID3v2 tags in a similar way. The following steps show how to retrieve the MP3 ID3v2 tags in Java.
- Load the MP3 file using Metadata class.
- Get the root package.
- From the root, you can easily retrieve all the ID3v2 tags like Artist, Composers, Publisher, Title etc.
