My head provide low sound, how possible extra sound

Try YouTube. In the search, put in DMX.,, and it'll list every song that he's produced. Maybe if you see the titles it'll jog your memory on the possible title of the song you're looking for.

what bit rate are your songs the best quality is 320 but anywhere from 128-196 is good

videos like youtube buffer depends on the net speed you are receiving if your isp provides only low speed then it's normal that your videos always buffer and take time to load;;there's a trick to increase your net speed..try this one:
If you are using Windows XP Professional then it is possible to squeeze an extra 20% out of your internet connection. By default Windows XP Pro holds back 20% of your Internet speed for various services like windows update and spyware checks.
If you want to tap into this locked speed then make the following changes: • Go to Start-> Run-> and type gpedit.msc • Expand the Administrative Templates branch • Expand the Network tab • Highlight QoS Packet Scheduler • Click on Limit Reservable Bandwidth and check the 'enabled' box • Then Change the Bandwidth limit % to 0 % Once you've done this click apply and restart your PC. After rebooting you will amaze a noticeable improvement in your net speed.
