Query: Don't buy until update is provided

I spent a week downloading and trying to listen to music I bought from various websites. Then I went to the iRiver technical support website and discovered that:"Currently the iHP and iGP do not support music purchased from download sites (e.g. Napster, BuyMusic, iTunes, etc). These music files are provided in a WMA copy protected format and the iHP and iGP cannot accept the license files required for transferring these songs to portable devices. iRiver is working on providing this support with a future update, please watch our web site should any details arise"
