What Are ID3 Tags in MP3s for my DJ Music Library?

Posted on 23rd August 2019

What are ID3 Tags?

Let's go back to the basics. If you are an aspiring DJ, ID3 tags will be essential to your overall set up as they allow info such as title, artist, track number, album or any other info that is key to that MP3 track.

Why Do I need to use them?

Without the obvious need for track info, the metadata in your MP3’s can be extremely useful when your mixing and on-set. The key to an easy DJ life is a meticulously organised music library, we know its not the most exciting part of being a DJ, but imagine having the perfect track to mix and you go into blind panic digging through your whole library to find its saved under the wrong name.

Whats the best way to organise my MP3s?

So if you are starting to dabble with the decks, do yourself a favour and structure your MP3 library sooner rather than later.

  • Make folders to collect tracks of a similar genre
  • If you have a live set coming up, make sure all your tracks you want to mix are all in one place to avoid searching the depths of your hard drive
  • Make sure your ID3 tags are labelled correctly 

If you find that some of your ID3 tags are incorrect, the editing process is quick and simple:

1) Start by opening your preferred media player and selecting the track that you would like to edit. If you double click on an MP3 track in a folder, it will automatically open and play in your default media player. 

2) Right click an MP3 file within your media player. Depending on the media player you use the options will vary, but in most cases you want to select “Edit” or “Get Info.” or any similar variations. In a few scenarios, there will be a “Find Album Info” option which will automatically fill in the ID3 tag for you (although it is still a sensible idea to double-check the information yourself).

3) Next, simply fill in the information required. The more information that you add, the better. This can include album artwork to improve the aesthetics of your DJ library, the year (if for example you happen to be doing a decade themed event) and any other key information such as artist, title, album, and genre. To ensure your tags are accurate, procure the information from a reliable source and obtain high quality images.

4) Once you have completed the ID3 tags of your chosen tracks, reboot your media player and check a couple of the tracks to ensure the information has been saved and stored successfully. An easy way to check is to simply play the tracks you have edited and look at the information displayed. Then you’re all set for a killer, stress free set

Alternatively, there are ID3 tagging apps and other software options available via a free download or small subscription fee. Some examples include:

TuneUp for iTunes
Automatic Tag editor for android

These can be an effective and easy solution to your tagging problems, but be sure not to skimp on a tacky software app as it may give you false tagging and ruin the structure of your library.
