Not sure what they are called but many games need music for stuff like

• starting a level
• getting a super power up
• getting a warning 30 seconds left
• player dying
• player winning
• players tying

Etc.  Just thought I'd ask. If you're looking for small things to do. Here's an open source game I've been working on that could use them http://goo.gl/XiYMtm

Player 1 is AWSD, Z to drop, X to show name

Player 2 is Cursor, B to drop, N to show name
