I, too, play and teach guitar (though admittedly it isn't my "job") and to say that the Beatles were crap in any facet of the music they created is absolutely ludicrous. Is it super difficult? No. Is it creative, and - at the time - new? Absolutely. To say it is thievery from Delta Blues shows that you don't even really understand Delta Blues, or the 60s Rock 'n Roll twist which they put on it (i.e., created). Many scales, predominant riffs and melodies cross, but they are not used in the same way. I saw a show on VH1 a few years back where they were interviewing Billy Joel and he commented on how he was in an elevator one day and heard a very familiar melody, recognized it as his own song (can't remember which one, but it was an 80s poppy one), elevator-ized, then had an, "OH, SH*T!" moment when he realized it was actually Bach. Did Billy Joel steal that pop song from Bach? Clearly not, but each piece of new music has elements of other music in it.And the Beatles didn't just dominate music, (14 songs on the top 100 at one point in 64), they changed the style of what was considered popular music (call it pure "Pop", that's fine). Check out the Billboard top 200 in 1962 or 1963 and then in mid to late 1964. See anything different?I would post my personal top 20, but it would likely turn into a top 200 or so (there are bound to be 5-10 songs that I could put on the "don't like" list). I will say that agree that While My Guitar Gently Weeps with Clapton is one of the best.
