Worst Rock Band Ever !!!!

The Shaggs!

Hard to say, there are thousands that couldn't be any worse .

This one has potential but still a bit wet behind the ears.

I would not have thought about Grand Funk Railroad or Blue Cheer as not being a good group, or even bad.  But now that you mention it way back then I would buy an album for a particular song, listen to the whole album once, and just play that one song repeatedly.  Just like mentioned above, Summertime Blues, or also Some Kind of Wonderful.  There were of course exceptions where the whole album was great, notably the Beatles, some Stones, on and on.

Actually, that was the great thing about CDs when they first came out.  You could program in the songs you wanted to hear and not need to concentrate on dropping the needle in that little groove between songs.  That could be a challenge at times, LOL.
