You need to log in to an Apple account, otherwise the audio will not be complete.

m3u8 URL: https://aod-ssl.itunes.apple.com/itunes-assets/Music211/v4/62/89/b9/6289b9e3-7f10-48ec...hq.aac.wa.m3u8

key in m3u8.file:
#EXT-X-KEY:METHOD=ISO-23001-7,URI="data:;base64,AAAAAGlI3QYAHb04q+XU8g=="

The downloaded M3U8 music file has no sound, it is encrypted.
Who can help me and guide me? What is ISO-23001-7 and how to decrypt using the key here?

just use widevine proxy2 or https://github.com/zhaarey/apple-music-downloader (the second one gets also alac but it's slighty more complicated to setup)

oh and unselect use shaka packager in the widevineproxy2 and change the format in the command from "format=mkv" to "format=mp4" and then convert it from mp4 to acc with something like ffmpeg

Is there no algorithm or method to obtain the key for decryption? Can it only be achieved through script injection and similar methods?
Also, I tried using Widevine Proxy2, but it cannot obtain the Apple Music key.

WidevineProxy2 works.

Don't forget to put L3 Cdm in the extension.

Ah, WidevineProxy2 worked! I didn't think it would work because I saw an error, but it really does work. Thank you so much!!!

I obtained the key, but when using the command line N_m3u8DL-RE "undefined" --key 000000006948dd06001dbd38abe5d4f2:d20bb0c49382c40ce 75ba83d1795c86f --use-shaka-packager -M format=mkv, it shows the error "ERROR: Object reference not set to an instance of an object."

I tried downloading the MP4 through the m3u8 file and then using mp4decrypt to decrypt it, but I found that the decrypted audio is still not playable.

Sorry, I had some difficulty with reading comprehension... I carefully reviewed what you said, and by adding the N_m3u8DL-RE command to the m3u8, it worked! I used the command N_m3u8DL-RE https://aod-ssl.itunes.apple.com/itunes-assets/Music211/v4/62/89/b9/6289b9e3-7f10-48ec...hq.aac.wa.m3u8 --key 000000006948dd06001dbd38abe5d4f2:d20bb0c49382c40ce 75ba83d1795c86f --use-shaka-packager -M format=mkv, and it successfully downloaded and decrypted the audio. Thanks again for your help!
