Recently when i try to burn a playlist to a CD, the CD is burned with the songs in al;phabetical order based on song name, not in the order of the playlist I made. how can i fix this?

WOW. That's a new one...

Something to do with having the shuffle button enabled.

Otherwise...

Are you sure you didn't accidentally hit the "Name" header before burning?

Does it actually PLAY in alpha order or are you looking at the disk in Windows explorer...?

If none of the above is true, the most likely possibiltiy is that the playlist is corrupt. (I've been using iTunes since V1- have over a hundred playlists and that's never happened) Anyway, there's no way to "fix" a CD once it's been burnt.

So... create a NEW playlist (you might even try with a couple different songs first just as a test) if that works, just copy desired songs to a new Playlist, and burn again.

If THAT doesn't work, it's possible your iTunes files (Library.itl / .xml) are corrupt. There's an article in the knowlegebase called something like "Recreate? or rebuild? your iTunes Library" that explains exactly where these files dwell, and how to reconstruct it.

Was this a regular audio CD, or was it a mp3 CD?

The apparent order of a burned CD may depend upon how you have iTunes display it - https://discussions.apple.com/thread/3797427?answerId=17827921022#17827921022

That's strange. Does it play out of order on cd player?

As suggested by my link above, which column header have you selected to display the CD? If you select Album then it should sort internally by track order. If you have selected the artist column then it will sort by artist regardless of the track order on the CD.
