Burning A Cd To Play On Portable Cd Player

[MichaelZZ]

I have recently bought a digital download of a classical music CD.
This was saved on my PC as a .mp3 file and plays perfectly well on my computer.
However, I would like to be able to copy this music onto a CD so that I can play it on either of my conventional CD players. I therefore converted the mp3 file to a .wma file (and also, separately, to a .wav). These new files I have saved into separate folders on my desktop. Both files play perfectly OK on my computer but when I burn them to CD using either WMC and Nero although the discs burn OK - and play satisfactorily on my PC, the CD won't play on either of my stand-alone CD players.
I should perhaps add that I have tried using both CD-R and CD-RW discs.
I am sure I have done this sort of thing before with 100% success.
Can someone pleas advise what, if anything I am doing wrong this time?
Thanks

In Nero did you select create 'Audio' Disk?

Thanks Pinky, I've tried both Audio disk and Data disk.

Did you finalise the disk?

Create the CD from the mp3 files and select Audio disk.

Audio CDs are written with a completely different format to data CDs so, as others have said, you need to tell it that it's an audio disc you are creating.
There is also a very good chance that your stand-alone CD player will NOT accept CD-RW discs, so try with CD-R discs.

Many thanks to you all!
I had forgotten that my CD players don't like CD-RWs and it appears that the CD-R that I tried yesterday was corrupted. I invested in a new stack of CD-Rs today and the job was done with no probs.
