If I'm generally fond of a particular style or genre of music, I don't demand that every piece be composed to the highest standards and performed at virtuoso level. As long as the performance seems genuine, I'll enjoy it.

I'll certainly listen to styles and genres of which I'm not generally fond if the material is obviously well-composed or performed extremely well, but it's gotta have something that really reaches out and grabs me.

In other words, I'll listen to a set of fiddle tunes any time, even if they're old chestnuts performed by a run-of-the-mill fiddler, but a saxophonist better really have his shit together or I'll listen to something else.
