How do i add music to my map? It can play on whole map or just by pressing some button. Help! and thanks 
Music on map
4MB mp3 sound will be like 10MB if made into a mono 22KHz wav file. usually i take out a good piece of music. in the game, there are many ways of making speakers etc. first, speaker that plays sound and when destroyed will stop(no script). make a box that looks like a speaker. make it func_explosive, make a target_speaker. give it the sound file, select the looped on spawnflag. connect the func_explosive with the target_speaker.(select func_explosive first, then target_speaker, hit ctrl+k)
speaker with button trigger. again make a target_speaker and give a sound file. make a func_button or func_invisible_user and connect them(again, select button first, then speaker and hit ctrl+k)
and many, many, many, many more ways. just ask!
select target_speaker and press sound on the entity info watever window.
then navigate to your .wav file
I needed to use http://www.btinternet.com/~AnthonyJ/projects/FixWAV/
To get my voice overs to work.
you can do the same in your sound edit program. i use nero sound wave but it doesnt export correct wav files :S. so i make my edits and save mono mp3. then in audioblast i make it 22000Khz mono wav
Iโve had good luck using Audacity to make my .wav files
I run Audacity on Linux but I believe there is a Windows version too.
