Don't add songs to iTunes library

I've tried loads of iTunes alternatives to simply play music files but none of them are any good

so I stick with iTunes player as it gets the job done.

Is there a way to prevent songs being added to the iTunes library?

I just want to use the iTunes players to play songs - that's it - without them being added to the library and thus taking up disk space.

I have separate folders to organise my music.

I know I can play a song from Finder using Spacebar but it automatically changes song when scrolling through other songs.

Quicktime player would be OK if it auto-played the song instead of having to open it, then pressing play.

Plus, opening another song opens another QT player so you have to close the current window or both songs will play over each other.
