Why are these type of questions off topic?
I think that some questions that ask for recommendations of pieces to play might be useful to future readers.
--I just started playing electric guitar/bass/drums and I'm really into rock/metal/punk, what are some beginner songs I can practice?
--I'm learning piano for some time now, but I've only been learning chords/intervals and some basic exercises (which are boring). Are there some simple songs that I could play?
The latter is something that has happened to me when I started playing double bass, and I believe it would be good if I had some simple songs to play back then.
