I have been using the music store on a daily basis before and after the intro of version 7. I have watched what problems that I have had personally and watched what problems the other customers have been reporting on the forum. I have a theory for some of our connection problems. It is only a theory, and I will probably get pounced on by other more knowledgeable customers for throwing this out there, but this is only a theory of mine remember.
I had some connection problems too before version 7, but not to the larger extent that I have had since the intro of version 7. I am not even running version 7 currently to try and avoid some of the reported problems on the forum, but I am still having connection problems. I only use iTunes for music and have "made the adjustments in my system" that could interfere with connections or cause slower downloads as other readers here have suggested I try. In fact, I am writing this because I cannot access the music store currently (I would much rather be browsing/buying music in the iTunes store rather than passing the time on the discussion forum). I have also noticed a pattern that is time sensitive (which might or might not have any merit). Evening after evening since version 7 has been out there, it SEEMS to me as though when the large contingent of west coast customers get home from work/school/etc.(about 5:30 - 6PT), combined with the fact that customers (anywhere/everwhere else east) that run version 7 are at the same time downloading higher resolution/larger video files (and also happen to be home from work/school at that time), that Apple's system currently MAY not have the capacity to effectively handle that much data being transferred during the "prime time" hours when the majority of customers are visiting the music store (before or after prime time are much better for connections and downloads I have personally noticed a pattern for).
Again, I may be WAY off with this theory. But at least it is a theory rather than just leaving it as a complete frustrating mystery as to what all of these connection and slower download problems are about (even for music only purchasing customers using previous iTunes versions). I of course have no solid evidence though which is why this possibility remains only a theory of mine. I am keeping my fingers crossed that Apple fixes any issues that might be causing these problems and that things improve soon.
