Album tracks and grouping

[Gogster]

New Winamp user here, so please bear with me.

How do I keep album tracks together? For example I ripped R.E.M. Out of Time to WinAmp and it displays 3 entries in the album list:

R.E.M.
R.E.M. Feat. Kate Pearson
R.E.M. Feat. KRS-One

This has been replicated on my HTC Desire. Is there a setting to sort this out or do I need to edit the album/track info?

Thanks in anticipation.
