How to add music to Macbook Pro but not iTunes

Hello

Today I finally bought my first Mac - a Macbook Pro - after being a PC user since forever.

I have nearly 300GB of music (sourced from various places) on my PC which I manage in folders - I don't like iTunes. I need to move the music to my new Macbook but I don't want to add it to iTunes.

Can someone please help advise me where on my Macbook I should save it and how to stop it from automatically adding to iTunes.

Finally, when it comes to playing the music, again, I want to avoid iTunes, so can anyone recommend a something similar to WMP I can use.

Thanks

PS if you're asking why not iTunes, well it's purely preference. I like to select a random selection of albums to play in random. Plus iTunes has previously cocked up my tags and folder structure so want to avoid
