Hi

If you go to the Limewire Library, you will find an MP3 player provided for a preview playing. Sadly, you cannot store a playlist on this facility. So that answers your direct question of "how to play files on Limewire". However, the previous post is offering the premium advice. iTunes is the standard internal player. If you were previously using PC packages like Windows Media Player, be relieved that you are no longer subjected to the spyware that notifies Microsoft of all the MP3s and DVDs that you play on your machine. I assume that you switched to Macs to avoid this invasion of your privacy.
