New music

I have really been into Japanese and Irish music the past few weeks. I need to start expanding from here. I love to listen to music and bands, even if I can't understand what they are saying. It lets me concentrate on the instruments and how the placement of the word are in the songs. I like to listen to this first before I learn the lyrics, otherwise I may not like the song because of the layout of the two. Does anyone have any suggestions to what I should look for? Maybe Germany or Italy. Oh! How about Josh Groban? I think I shall start there. haha
