Soft music with hard rock / metal highlights?

[DynV]

I'm--not--looking for slow or softer rock (eg the latter avoiding everything found in grindcore). From time to time I listen to soft music, which is mild enough that when you do something requiring attention, it distract very little; or when tired will cause little-to-none delay to sleep. Listening to the channel Lush of soma.fm, I stumbled on Cavestar - Don't Let Me Go and I love the hard rock / metal highlights, do you know of something alike?

Thanks

There are some good one's which I can remember enjoying so much. Here's my recommendation.

1. The Thin line between love and Hate - Iron Maiden.

2. Beyond the realms of death - Judas Priest.

3. I ain't no nice guy - Mötorhead.
