Not sure why you would choose wma over the more popular formats, but ripping is the beginning of the process; not the entire process. The info concerning genre, artist, album, etc. is contained in the meta-tags of the file. CDs generally don't have meta-tags. So if it's ripped from a CD, there will be no info. There are programs that can sample your ripped files and likely find the correct meta info and insert that info into the file so that your player can read it. MusicBrainz Picard is a good one. I don't use Windows, but I believe there is a Windows version of Picard. For future purchases, you might investigate HD audio downloads. They are not cheap or small (1.2GB per "album"), but generally have double the resolution of an audio CD. HDTracks is just one of many services for high quality audio.
