When you listen to a song after a gap of more than fifteen years, two things happen: a) you rediscover the smoothness of the music and the fantastic guitar riff and b) realise that there are things in the song that you didn't even pay much attention to earlier, like the Hey! This is mine! in the middle that you now belt out lustily along with good old Sammy Hagar.
I have listened to it six times already, and I predict that the song will lose all its appeal by some time around 10 PM tomorrow :-)
