I don't think this is a totally fair comparison, because anyone who knows how to code their own site (/service) is already at a major advantage.
Now, if you downloaded an off-the-shelf MP3 search engine package and merely hosted it, it'd be different.
I also don't think that surviving a sudden upsurge in traffic is a particularly impressive feat just because it's Wordpress. If anything, it highlights how inefficient Wordpress is, which might possibly be a result of trying to be easy to set up. And a lot of the people who do use it don't realise how much worse they make it by adding plugins.
