It takes about 1 to 3 seconds to update an Ogg tag... Instant for an MP3... For everything there's Mastercard.... what no, that's not right.

So yes... it's very easy to reproduce, I couldn't see anyone else having mentioned this in the tickets... my music 99% Ogg Vorbis and thus it takes aaaaages to update the tags if they need changing.

Could perhaps we look in to why or maybe change to a quicker method of updating Ogg tags or bring it more in-line with the speed you get on updating an MP3 tag?
