Odd coverflow glitch and music playing issues

Question

I'm having an odd problem with the coverflow on my ipod where some album covers appear as a pixelated mess. Also i have an issue where during the song (or at the beginning) it will go quiet for about 20 seconds or more and then continue playing effectively skipping 20 seconds of the song or in some cases the song will be not play at all. I have a 4th gen ipod touch running iOS 4.2.1, i recently had some trouble performing a restore (itunes error 37 =s) and it took near 5 attempts to get my ipod restored.
Any help is appreciated

Thanks for response.
This was not an issue with any iPod in the past, but I usually list my albums in more a category way than the actual album name.
With over 3000 songs, many one song from an actual album, I'd have so many albums it does not make a lot of sense (to me) to organize one's collection that way.
So I listed my albums as: Rock, Folk, Jazz, World Music, Classical, etc., etc. That helped (me) organize the large collection better. So maybe Coverflow in the iPod Touch 2G is reading all these categories only once. I don't know why - as I said previous iPods I've owned (Incl. the Classic) showed each artist and "album" in Coverflow.
As I say, I saw no point of listing by actual album names as much of my collection is not by an actual album, by a song or two from each album.
However, my way of organizing helped me. If I just wanted to hear Rock (and not Classical, Jazz, etc.), I would just click to play my Rock album.
Under Genre, I would break it down further. For example, under my World Music 'album," I would list songs by country: Mali, Italy, Cape Verde, etc., etc.
At any rate, I wonder if this is the glitch under iPod Touch 2G - it only reads my album categories once and just lists the first song only under each.
