Cordless phone with Megadeth’s “This was my life” as a factory preset ringtone!

Oh! I've just discovered this! I have this phone in my house for about 2 years, today I wanted to put a different ringtone for a contact and found it! There are 15 factory preset ringtones in this phone, but the ringtone #11 is just like that riff from the Megadeth song "This was my life" from their '92 album "Countdown to extinction"! The phone is a "Hi-Tel HT2700"

The second song have been played on my cordless phone by dialing. Can you guess what song it is?
