Sì, questo è possibile. Una volta che il cloud ha abbinato la tua canzone bitrate più bassa, fai un backup finale ed elimina quel brano dalla tua libreria di iTunes. È quindi possibile scaricare nuovamente la versione "standard" dai server Apple.
Jason Snell ha un ottimo write-up su un modo semplice per tieni traccia dei brani utilizzando la potenza delle playlist intelligenti:
Make a Smart Playlist Create a Smart Playlist with the following attributes:
- Bit Rate is less than 256kbps
- Media Kind is Music
- Any of the following are true: (to create this conditional, option-click on the plus button in the Smart Playlist window) iCloud status is Matched, iCloud status is Purchased
Delete all those files Select all the tracks in your playlist, and then hold down the option key while pressing Delete. Be sure to not select the box that would delete them from iCloud!
Bring ’em back All those tracks should still be [in the playlist]—but now they’re marked as being available only in iTunes Match. Select all of them again, then control-click on the selection and choose Download.
