MP3 decoding was already free and got recently included in Fedora. But now, encoding is also free according to Fraunhofer Institute for Integrated Circuits IIS: "On April 23, 2017, Technicolor's mp3 licensing program for certain mp3 related patents and software of Technicolor and Fraunhofer IIS has been terminated." The Wikipedia MP3 article confirms that.

So, do you still use an MP3 library or have you switched to another format or means of listening to music such as (spying built-in) streaming services?

    As the other poster pointed out, you're not quite right. We haven't needed dedicated MP3 decoders for a long time (even the original iPad didn't have one) for performance, but you really don't want to be doing audio playback on a general-purpose ARM core if you value your battery. When a phone is playing music, it typically wakes up the CPU, loads a track into RAM, kicks the DSP and then sends the CPU back to sleep. The DSP uses around 10% of the power of the CPU to decode the audio and will stream it from RAM to the ADC or Bluetooth device.
