In December there are free downloads of single tracks available at the Danish Dacapo Records site. Note that it's mostly Danish classical music - or Danish musicians/ensembles.
If you like to play around with higher resolution FLAC/WMA and just need some well recorded free samples there are several titles with "Studio Master" in e.g. 24bit/88.2 KHz.
