For many reasons;
when i take cds from friends ,i do not take just few cds ,i take TONS of cds.
In this case you cannot keep it a long time.
So APE or WMA9 lossless the solution because fast and lossless.
Now i use the WMA format ,because i think one day a kind of Ipod reading a lossless format out.
In this case ,i am sure it would be the WMA format.
The other reason i use WMA 9 is that MM superTags works with this format.
In no time i get the sleeves from it and know the sleeves i have to try to find on the net ,or scan.
Like it ,i can give back 200 ,300 or more cds back after few days.
After that ,i have all my time to make the 2 convertions.
The OGG are uploaded by a friend from my ftp site.
When a player out ,i will download from him the same songs , but WITH sleeves ,tags ,comments ect ect.
At this time , i keep the mp3 on my computer.
To make cds to friends and family and back-up for me.
When listening to the songs ,i delete ,or no the mp3 and the WMA.
All the albums i do not like ==delete both formats
Albums i like == keep mp3 ,delete wma
Albums i love == keep mp3 and wma
Concerning my cds ,i still rip to wma ,or Ape and after convert to mp3 and ogg.
The ogg are uploaded by......mp3 keep on my computer and lossless format deleted because i still have the original cds.
Here all the process.
