Macworld's Jason Snell has written up a quick way to force your local Windows or Mac iTunes library to upgrade all your songs to their 256kbps iTunes Match versions.
While iTunes Match makes often higher-quality tracks available in iCloud, your local—often lower-quality—track remains unchanged unless you say otherwise. If you have thousands of tracks to upscale, that could be a long and arduous process.
Snell's tip involves creating a Smart Playlist or two and having the courage to delete your local versions, trusting that iCloud Music Library will replace them. If that doesn't scare you off, hit the link below and get your upgrade going fast.
