Out of interest. I've started this about a week ago. Ripping CDs to lossless Wav Then encoding them to loseless FLAC - http://flac.sourceforge.net/ - being that it's Open Source (Unlike WMA or ALAC) & has other neat features, e.g. streaming support, good software compatibility. Then use foobar2000 to Replaygain & Freedb the tags. foobar2000's built-in "Convert" feature they can be easily transcoded into other formats as required, MP3, Ogg Vorbis, etc. for taking to work on my MP3 player. No need for me to keep CDs at arms length About 14GB used up so far.
