Besides listening to music that has more details, although some may not really notice depending on the audio equipment it's played on. One enormous advantage to lossless audio is you have a copy that is not lacking any details.
This means you can save it or archive your music for later use in full fidelity. Mp3 while smaller, is compressed and will not provide the same quality as lossless audio files. But the trade off there is mp3s are one third as small as a lossless file. So while you gain on bandwidth and storage with lossy files, the audio quality will never be the same as the orginal copy.
For most people listening to music through ear pods on their iPhone or Android phone, you won't notice the improved sound quality. But if you want to stream music files on a higher end audio system, the difference in sound quality between lossy and lossless audio is stunning.
