using real player to transfer music

I recently bought the 2nd gen shuffle and I have been
trying to put my purchased songs via real player on
it. When I transfer the music using real player, the
ipod sees it but when I try to play it, the ipod
blinks green orange meaning there is no music on it.
When I put imported music from a CD, it plays no
problem. I never had this problem with my 1st gen
shuffle. Can someone please help. I also tried
putting my purchased real player music in ITunes, but
that doesn't work either. Any thoughts on why my
purchased music from real player won't work on my 2nd
gen shuffle?

That's easy...Shuffle doesn't play RealPlayer music.

The following audio file formats are supported by iPod shuffle. These include formats for audiobooks and podcasts:

AAC (M4A, M4B, M4P) (up to 320 kbps)
MP3 (up to 320 kbps)
MP3 Variable Bit Rate (VBR)
WAV Â AA (audible.com spoken word, formats 2, 3, and 4)
AIFF

That's easy...Shuffle doesn't play RealPlayer music.

Does that just go for the 2nd gen shuffle? Because my
1st gen one does? Thanks for the help

News to me... Page 13 of iPod Shuffle (1st Gen) Users Guide:

Audio File Formats Supported by iPod shuffle
• AAC (M4A, M4B, M4P) (up to 320 Kbps)
• MP3 (up to 320 Kbps)
• MP3 Variable Bit Rate (VBR)
• WAV
• AA (audible.com spoken word, formats 2, 3, and 4)

A song encoded using AAC or MP3 format has near CD-quality sound, but takes up much less space than a song encoded using AIFF or WAV format. When you import music from a CD using iTunes, it is converted to AAC format by default.

Using iTunes for Windows, you can convert nonprotected WMA files to AAC or MP3 format. This can be useful if you have a library of music encoded in WMA format. For more information, open iTunes and choose Help > iTunes and Music Store Help.

iPod shuffle does not support AIFF, Apple Lossless, MPEG Layer 1, MPEG Layer 2 audio files, WMA, or audible.com format 1.
