The size of music files may vary greatly from different parameters such as bit rate and channels. If you are not as discriminating as some music enthusiast, the 192 kbps bit rate is enough for quality. So how to reduce the size of music files? See the specifics below:
1. First go to iTunes > Preferences > General > Import Settings > MP3 Encoder and set quality to Higher Quality (192 kbps).
2. Create a Smart Playlist from File > New Smart Playlist.
3. Set "Bit Rate is greater than 192" as the criteria to find out all matched music files.
4. Select all music files by Command + A or dragging.
5. Right click and select Create MP3 version. This will take a lot of time if your music collection is very large.
6. Go to Library > Music and show duplicates by File > Display Duplicates.
7. Sort by Bit Rate (If bit rate column doesn't appear, right click on any column and select Bit Rate. You are recommended to repeat this process to show Size column to see how much size is reduced for each music file - from 256 to 192, about 3MB - each song. )
8. Delete the larger music files.
Be default, your media files, such as video, TV shows, music, podcasts, are stored in the same iTunes library.
