Query: Protected content limits usefulness of music

After wasting a lot of time trying to add this CD to my computer hard drive media library in the format that I prefer, I gave up. The CD only lets you rip it to your computer in a protected, inferior quality wma format. If you try to rip it as an mp3 or lossless file, it plays all "jerky" and "skippy". If you want to listen to this on an mp3 player that doesn't accept wma files, forget it. What a joke. I'll never waste my money on another "protected" disc. Answer this, what exactly did my $14 buy?
