Peter, just been checking out the Mac OS app. Really, really like it. Syncing my N900 with it now. Not sure if you're also developing the desktop client or just the mobile one?

Anyway I thought I'd leave some feedback re: the desktop client.
1) Album art downloading is absolutely brilliant. There are album covers there I haven't seen ever through checking with both iTunes and Songbird, which are meant to be pretty premium media players.

However, when I scroll through my list of songs, it takes a number of seconds before the album art correctly shows up. Is there any way to eradicate this? I assume that the files are being saved and stored, as opposed to constantly fetched from the internet? If not, this is something you should definitely look at.

EDIT: Just searched through the Instinctiv file programs and found where artwork is indeed saved. Seems to load up a bit quicker after the update as well. Player now is very, very nice. Some artwork is missing that really should be found - for example, a band called Jet, and their album 'Get Born' cannot be found. However, I'd say around 75%+ now has an album artwork of some variety, which I'm very pleased about.

2) A feature I would really like, but I'm sure is difficult to implement, is the ability to write the fetched album art to the ID tag of the song. As I said, I'm sure this is a difficult process, but do you think it is a feature that might be implemented in the future? I've looked around for a free art-fetching, tag-writing program on Mac OS and have found nothing. If Instinctiv could do this it would have a unique position and another big 'selling' point, so in that sense there is something in it for you guys too (apart from providing consumers with a top-notch player).

3) It would be nice if there was a way to set up a 'watch folder'. I don't think iTunes does this - at least, it didn't last time I used it. But Songbird does. Basically the client watches for changes made to a folder and when it finds them, it adds them to the library. I'm not sure how much development is going into the desktop client as opposed to the mobile version but it would be nice.

4) I have been syncing with my N900 for about five minutes now and the progress bar is showing up nothing. Is syncing properly implemented or is this still a work in progress?

I can't tell you enough how good the album art fetching is. Seriously, most of these album covers I have *never* seen before. Absolutely top job, and I hope the updates come frequently because this is becoming a ripper of a player.

EDIT 2: It would be nice if there was a way to add album art from file, as mentioned in the first edit some albums can't be found that should be. Also, obviously this is one for the future, but a couple of different views (for example a list view) would be nice too, just to maximise the number of music files on screen at once. As I said though, these are not 100% necessary, especially not at this stage. These are all just features I'd like to see at some stage, and would leave little need for other players. I love how lightweight Instinctiv is at the moment, very nice work guys
