I thought transporting a playlist would be complicated but man it's super easy and takes nothing but 15 seconds to edit. It's awesome. Thanks for all your help in this!
Now that I don't have to worry about how much space I have am curious about bit stream. Normally I will download music that is 320kbps and change them to 192kbps to save space on my iPhone and hard drive but I'm sure there is loss in quality in that (not much but maybe a tad, don't even know if it's noticeable) . So I suppose my question is, if I took a 320kbps song and converted it to 192kbps, can I change it back to 320kbps an not lose any quality? All my songs are 192, if there that much of a difference between 192 and 320, is it even worth the trouble of doing that?

Alright thanks, not a big deal they are at the very top and my play lists are below them. So it's easy to ignore. Oh man I wish I got this SD card a long time ago. As soon as my car turned on there was the last song I played, no delay, no loading issues, sounds is great, man this is 10000x better than attaching my iPhone to the car to stream music.

To answer your question about whether it's even worth it to bother going back to 320kbps from 192kbps, that's a question only you can answer. Many will tell you that they/we can't tell the difference between the two. They are mostly correct, especially given that our cars are not ideal sound environments. However, where you will undoubtedly notice the difference is at higher volume levels.
I would recommend using the highest bitrate you can and lossless if possible, simply because it's a lot of work to rip cd's and if you go lossless, you only have to do it once. Then maintain a master copy and reencode copies of the songs to whatever bitrate suits your needs.
However, I stopped buying songs online several years ago and have been ordering the cd's on amazon ever since. That way, I've always got the cd and if the worst happens and I lose my media server and the backup copy on my home computer. Interestingly, I often find the cd is actually cheaper than the mp3 album on amazon.

No unfortunately, you can't go back up in quality. All you will end up with is a file that's as big as the 320kbps song but has the sound quality of the 192kbps file or worse. You should always save a backup of every song at the highest bit rate you have, then make copies at the lower bit rates as needed.

So I'm still experiencing wrong cover art every now and again despite the mp3 actually having the right cover art. As you can see below the song "No" has cover art for the song "Better" but when the actual MP3 file is looked at is has the correct cover art. Very strange.
Right song wrong cover art
What the cover art should be
Cover art used from the wrong song same artist.

I'll do some more exploring on this issue. Just curious if I was the only one. Those songs are pulled from a playlist, so I wonder if that has anything to do with it. I have 3 of her songs with different cover art but all showing one cover art in the MMI. Very weird. I'll try playing it from the album name or artist name and see if it does the same thing. As I said I wonder if it being played out of a playlist has anything to do with it. Troubleshooting...FUN, how I want to spend my weekend.

Just as a PSA. You can export playlists from iTunes to SD card for playing using the playlist menu in the MMI. Below is a link for Mac users on what the process is like. For PC users it should be the same but the save part in step 7 should not be needed as the txt should already be formatted for CRLF. As such Windows users can use whichever text editor it includes. For Mac users though you need to get a program that allows to change the format of the line breaks. I used the Text Wrangler app and it worked like a charm.

For clarity:
This format gives me an error:
#EXTINF:226,Rock 'N' Roll Is King - Electric Light Orchestra
\Music\Electric Light Orchestra\Secret Messages\10 Rock 'N' Roll Is King.m4a
But format worked fine:
