Audio playlist software

[harm_less]

Seems that we have a few IT savvy peoples around here.

I've been putting together a music list for an event I'm organising in a couple of weeks. I have somewhere around 1,000 CD albums ripped to my HD from which I've copied a selection of music suited to the attendees to a file. Original format is WMA but I'm able to convert to mp3 if required.

The problem I'm having is that using Windows Media Player is that the functionality is pretty ropey and the playlist I've compiled needs some editing and WMP is doing some pretty random shit in this regard.

What I'm after is something that will allow me to have a reliable file that is ready to play from my laptop into the venue's audio system. What's going to suit my purposes?

I've done that in the past streaming a Spotify playlist that I put together for the occasion.

A lot of the music I have wouldn't be available on Spotify, or would at least entail a lot of faffing around finding it. I already have the music I require but just need an elegant way to make play how I want it. Selecting extra tracks, deleting others and putting the tracks in order.
