If they are pop songs, see if you can get karaoke versions - they will have the vocals taken off. Try http://www.cookies.co.uk/ and see if they can help.
On a stereo mix, the vocals are usually in the centre. If you load the file into a wave editor you will see two waveforms, one for left and one for right. Select one of them and 'invert' it. This should cancel out anything in the centre of the stereo picture and that is generally the vocals.
