How do I join mp3 tracks together

I want to join a couple of mp3 tracks together to make a big long song that includes a couple of songs on the 1 track.
The program I want to use it on will only pick up 1 track at a time but I want it to play a couple of songs, hence I want to join then together to make them look like one long song.

Would be grateful for some help.

Well... I know that Windows Movie Maker allows you to make a slideshow with as many tracks you want, and you can cut parts of pieces from the song. Play around, and maybe you'll be able to do it without a slideshow or adding any images.

Thanks for your help.. That worked very well. I did it a long time ago and couldnt remember how I did it.

No problem.
