does i tunes match work without an internet connection, like if you are out of service

Hi stockd,

Thanks for visiting Apple Support Communities.

iTunes Match requires an internet connection, as mentioned in this article about how to subscribe:

If at any time during the matching and uploading process you lose your Internet connection or experience a power outage, iTunes will automatically resume where it left off the next time you open iTunes.

See the full article for more information about subscribing to iTunes Match:
