How to change, set Album, Title, Artist, Genre etc in my music collection?

"I collected some musics in folders from various CD's, that has Album, Title, Artist, Genre etc different"

They're in their own folders based on album, artist, etc? That's not really necessary - you can define that info for each file by changing it's properties. You don't have to scatter them.

You can change the information of a number of files at the same time by highlighting them right clicking on them and choosing properties. You can do this in iTunes as well - block up all the files having something in common (artist, album, genre) choose get info then enter in that common artist or album name or genre. iTunes also lets you enter track numbers for each song - be sure to put a "0" in front of each number for all tracks from 1-9, or it will skip from 1 to 11 (and keep going up to 19, or as high as that nuymber goes, before track 2).

"If i need to burn/publish in CD then whats the procedure?"

Are the songs purchased through iTunes? If so, you can probably burn a CD using it - however, I burn Audio CD's using windows media player. Just choose th eburn option, drop the tracks into the playlist and hit burn.

If you want to play more than 7-80 minutes of music on a CD, and your CD player supports mp3-CD (and if you have MP3 files) just copy them to the blank CDR. Insert the CD and open up seprate windows explorer windows - one for the folder containing the songs, and the other for the CD. Block up all the songs you want on the CD, then use the mouse to drag them to the blank.

If u r using iTunes right click on the album and press get info now you can choose whichever one u choose

im assuming u have windows

right click the song and click properties, then the details tab and edit away...

for the burnign, just drag these songs onto an empty cd and click burn

(click music disk if it asks)
