Thankfully I've been rendering my OHB entries occasionally (and usually I do the oldest songs first, although sometimes I do non-looping songs as well ahead of the others). Otherwise it would be a much larger TODO list. I usually render them myself, but if someone else does render them, be mindful of the loop points... some of them are very tricky. Besides, I'm the one that can make infinitely increasing tempo songs (well... kind of... up to 255).
Speaking of that... if I had not rendered my first two ZX Spectrum entries, it would have been next to impossible for me to get them to work again due to cluelessness on loading the files after saving them. :(
