Yo Gunther: [isn't that a beer?]
I don't know if FAKE BOOKS are still around. I have a few of them and they contain standards and songs not so standard. The real old ones give the name of the Musical play the song comes from and they contain WORDS.
I'm sure there must also be a rock fake book or books out there too.
I remember I got one for a musician friend of mine once and brought it to him while he was doing a gig. And, wouldn't you know, a real wise guy walked by the piano and said, "Hey, kid, can you play "All the Things You are"? He was an excellent reader and asked me if that song was in the fake book--it was. Last words from the wise guy were, "Oh, he can read." The song is a bit tough to play for most musicians, even today.
One fake book would give you a couple of hundred songs to mull over. Just the lead note and basic chord changes for most of the books.
Saves a bunch of $$ buying sheet music.

And, if you are a member of ASCAP, you may still be getting song-cards by the bunch.
