My first post

A super site you guys have going

Glad to finally be a part of it.
I've heard songs like Chilli Cha Cha, Todo Todo, Sexi Dance, Need to Know etc. which come under what is considered suitable for the Cha. Personally i find them too rigid in their form, which is not to say i dislike them. I just find the feel to be a little ..mmm...regimented?
My question is: What rhythm/category/style do these songs (the ones listed under here) come under? Are the songs I'm listing here cha cha cha's? If not what are they? I'm more interested in songs with this rhythm irrespective of whether they are cha's or not.
Vertical Expression of Horizontal Desire - Bellamy Brothers
South of the Border - Dean Martin / Chris Isaak
Ticket to Heaven - Dire Straits
Diesel Cafe - Dire Straits
Tequila Sunrise - Eagles
When you're only lonely - J.D. Souther
What are these? Does anyone know of any songs with a similar rhythm to these? If you do please lemme know! Am i wrong in thinking these are all cha cha cha's of some sort? Any info would be appreciated. Thanks in advance!
