METAL COVERHEAT, as the name tells, is a radio show that talks about metal music and is exclusively devoted to music covers. First, the name cover has a double meaning :
1. The cover of an album or a CD or a demo means the front image of the record.
2. But a cover also means that a band chooses a song from another band and plays it sometimes equal or sometimes changing rhythm, style,.. It's, of course, this definition that gives its meaning to METAL COVERHEAT.

Then Overheat means excited, frenetic or is about a motor becoming hotter and hotter.

So the word COVERHEAT is just a word created by his designer with the contraction of cover and overheat, you could have guessed !!!
