Number One is that old classic from Allan Sherman. Do they still have summer camps in the USA? It's a great piece of humour and very seasonal.
The Castillo Kids are highest new entry at 6. I've come across them on Youtube. Some of their covers are a tad cringe-worthy, but they usually hit the right note with Latino numbers. This one is an original and I particularly love their guitar work. This shows the best side of the Castillos and fits in well with the current sunny climate.
Phil from Germany at 14 has a quality song which I think deserves a large audience.
Billy Irvine's song at 17 reminds me of those late 60s early 70s pop rock numbers which used to send a tingle through my young body. Cool stuff.
The Talent at 19 rise just a touch above other Indie bands. I like the song. It has a slight quirky feel, rather akin to the Bare Naked Ladies.
