Got this idea from the other dude who's posted a couple of these threads now.
Personally, no matter what band, I cannot choose just one or two songs that are my favorites; I like so many of them haha.
In memorial for Ronnie James Dio who died in May of 2010 and what would have been his 72nd birthday this next July 10th; here's a thread for him!
A number of my favorite Dio tracks are:
Don't Talk To Strangers
The Last In Line
I Speed At Night
King Of Rock & Roll
Why Are They Watching Me?
Bring Down The Rain
Killing The Dragon
As Long As It's Not About Love (Sad song that I sing along to every time)
Lord Of The Last Day
Dio was 62 years old in this video (starts at 0:42), he was amazing! Had his last performance at the age of 67 in 2009 & still sounded amazing.
And here's a video of his final performance, which took place with Heaven & Hell (Black Sabbath) in 2009:
