The best way to identify how your music file is actually constructed is to use a Windows program called MediaInfo. After you install that, you right click on the song file and select MediaInfo. It will then tell you info like the container, the codec used, the bitrate, etc. etc. It works for any kind of multimedia file whether it's a video or an audio file. You can copy and paste the info so it makes it easy for people to know what's wrong.

As for album art, it's best to add it yourself. When you purchase a song legally, the album art is embedded in the file already. Most ripping software (when you make your own MP3s from CDs) will have a system for importing album art and embedding it. If the album art is not embedded, you can manually add it. I use a program called Tag Scanner. It can search for album art. Or best yet is to google/bing the album art cover and then use Tag Scanner to add the art to your MP3s. That way, no matter what media player you use, it will have the album art.
As for whether songs will play back or not, the music app supports all standard audio codecs. If your songs are using a specialized codec like FLAC, it will not play. That's another reason to use MediaInfo to determine what your songs are using.
