adding music to powerpoint

[Mandalin25]

[please respond to [email]amanda_Frank@hotmail.com[/email]]I am putting together a slideshow that will include several songs. How many, I am not quite sure of yet. I plan to plug the songs in as I go, however starting out...I have a first slide and two slides following. I have added a sound link to the first slide. It is having that link continue to the rest of my chosen slides that I am having the problems with. I have followed the instructions that I received below, however I do not think my music files are WAV's or MP3. How do I get them converted? or am I going about this the wrong way?
HELP!

And if you use PowerPoint 20002/XP or PowerPoint 2003
Go to the slide where you want the sound to begin playing
Choose Insert, Movies and Sounds, then click Sound From Clip Organizer (or Sound From File) to insert the sound. If you don't want the sound icon to appear in the slide show, drag it just off the slide.
Say yes when asked if you want the sound to play automatically. If you are not asked this, don't worry, the next steps will let you set that (or double-check the settings if you were asked and said yes.)
Right-click the sound's icon and pick Custom Animation from the popup menu. The Custom Animation pane will open and your sound file should be listed.
Click the arrow directly to the right of the sound icon to pull down the various options.
Select Effect Options, and on the Effects tab, click the radio button beside Stop Playing after *** slides. Put 999 in the box so the track will play throughout all your slides, even if you go back and forth among slides. PPT
considers each transition a "slide," so you want to put a large number in there.
Now check the settings in the Timing tab. To play automatically, the timing should be set to Start After Previous with a 0-second delay.Click OK to close the dialog box.[/quote]
