People familiar with the latest build indicated it contains some of the same issues that were present in the previous beta of iTunes 10.5, supplied to developers earlier this month. The largest is said to be the incomplete music scanning feature that will be a part of Apple's $24.99-per-year iTunes Match service.
In its current form, some tracks reportedly won't be recognized through iTunes Match, and will instead be uploaded to iCloud storage. The iTunes Match beta is available to developers in the United States.
Developers were also warned that music may not play if an iPhone, iPad or iPod touch is updated to iOS 5 beta 7. This can reportedly be fixed by turning iTunes Match functionality off, then back on.
Any iCloud libraries created in beta testing iTunes 10.5 will be deleted once the beta has ended and iCloud is publicly available. Developers are said to have been advised to back up regularly and not delete any local music that has been synced to iCloud.
iOS 5 beta 7 was supplied to developers in August, and soon after the iTunes Match beta was expanded to more people for trial ahead of the upcoming iCloud launch. iCloud is expected to debut alongside iOS 5 and iTunes 10.5.
That launch could come as soon as next week, as Apple will hold a media event on Tuesday to introduce its next-generation iPhone and refresh its iPod lineup. The keynote will begin at 10 a.m. Pacific, and AppleInsider will have full live coverage.
