Musik theme

I love this theme, but I have been having trouble with it. It takes entirely too long to upload & some friends have left messages, but I don’t get them. I need to change & I can’t afford to get a good one. I have to settle on a freebie, but I don’t know which would be best for me. Can someone look at my site & help me? I also want to add audio player, my site is oldtimerockroll.com.
Thank you in advance,
Peggy
