.wav to .flac conversion using MAC OS X


I'm exhausted from looking on the net without finding a solution and I need your help. I have 300GB of .wav files stored on a hard drive after spending a long time ripping my CD collection. I need to convert them to .flac and save them on another drive for backup. I used xACT to do the conversion and things were great until I added the albums (I did one album as a test) to PLAY, a music software that plays .flac files. The songs were added without any properties (name, album, artist). Please keep in mind that the files are stored with the names example Money.flac.
If any one has come across a similar problem and found a workaround, please help me.

thanks,

Ksalous, why are your original files in WAV? If you have to manually enter streams of data, then you really aren't backing up the files. Your method has really complicated what could have been a simple process. I think you should consider starting over again and doing it the right way.
I agree with restock. iTunes & Lossless is the way to go. Do a batch conversion and just move the newly created files onto that backup disc.
There's also another free OS X program called "X Lossless Decoder", or XLD. I have never had to convert wav. to flac so don't know if the metadata will be preserved, but for general conversion or splitting ape with cue tracks it is great.
