Accessing Mp3 Metadata with Python

Python: How can I access an mp3 file's metadata using Python?

There's a module called Python-ID3 that does exactly this. If you're on a Debian/Ubuntu box, its package name is python-id3 and there is example code on its website:

from ID3 import *
try:
    id3info = ID3('/some/file/moxy.mp3')
    print id3info
    id3info['TITLE'] = "Green Eggs and Ham"
    id3info['ARTIST'] = "Moxy Früvous"
    for k, v in id3info.items():
        print k, ":", v
except InvalidTagError, message:
    print "Invalid ID3 tag:", message

How to read ID3 Tag in an MP3 using Python?

Dive into Python uses MP3 ID3 tags as an example.

How to get a custom MP3 tag via Python?

Yes, you can use either one. These custom tags are stored as user text frames, with the frame ID "TXXX".

Here's some example code with eyeD3:

import eyed3

file = eyed3.load("test.mp3")
for frame in file.tag.frameiter(["TXXX"]):
    print(f"{frame.description}: {frame.text}")
# get a specific tag
artist_id = file.tag.user_text_frames.get("MusicBrainz Artist Id").text

And with mutagen (it supports multiple values in each frame, but this seems to violates the ID3 spec; see this picard PR for the gory details):

from mutagen.id3 import ID3

audio = ID3("test.mp3")
for frame in audio.getall("TXXX"):
    print(f"{frame.desc}: {frame.text}")
# get a specific tag
artist_id = audio["TXXX:MusicBrainz Artist Id"].text[0]

You can see how Picard uses mutagen to read these tags here: https://github.com/metabrainz/picard/blob/ee06ed20f3b6ec17d16292045724921773dde597/picard/formats/id3.py#L314-L336

How to extract Encoded by from mp3 metadata using Python?

It turns out the "Encoded by" field is buried in a list returned by the frame_set object: audiofile.tag.frame_set['TENC'][0].text

Trying to access id3 tags of mp3 songs from a folder using a loop

Now that you typed the full error message the error is clear:

No such file or directory: '01 California Dreaming (copy).mp3'

That means that the call is correct but the file name you are using does not exist. You are thinking: "but it came from os.walk() so it must exist!". Well yes, but os.walk() returns a list of tuples, each of three values: root, dirs, files. The files list of names are the filenames in the root directory.

Solution: you have to concatenate the root and file names:

for root, dir, files in os.walk("home/undead/ShareWindowsTest")":
    for file in files:
        path = os.path.join(root, file)
        audiofile = eyeD3.Mp3AudioFile(path)

PS: Are you missing a leading / in your os.walk("/home...)?

Extract ID3 tags of a MP3 URL using python

You can do a partial download: Download file using partial download (HTTP) (if the server supports it)

on rereading, and seeing joelhardi's comment, this is even easier:
