Why are TNA entrance themes really bad?

It's kinda funny to start a thread that is seemingly asking a question, but not a balanced question. Some of their themes are quite cringe-worthy, but this hardly means that all TNA entrance themes are really bad. However, as this is a thread about opinion, I guess I'll give mine.
For those that remember Daniels' old non-Marilyn Manson 'Beautiful People' music, this may give an insight as to where the problem lies. MM's version of Beautiful People is a personal favourite of mine from the angry teenage years, but aside from that it was used by SmackDown! as their promo music in the early 00s I think. What I imagine happened is that they added the intermittent 'hah hah' chanty bits to make it sound different enough from the original. Whilst a good idea, the execution came off a bit cheap. The way I see things, you could use this explanation of 'good idea, poor execution' to a lot of their musical (and yes even their wrestling) ideas. However some themes, previously mentioned are the exception to this, Beautiful People's music being an example.

WWE does put a lot of stock into being able to use songs from established musical people though, be it Saliva, Motorhead, Killswitch Engage, Age Against The Machine or whomever, but some of their new themes are fairly terrible.
Sheamus' music actually starting with the line 'It's a Shame...' is really really bad writing seeing as they're making a pun on the guy's name.
Legacy's opening bit of guitar is pretty cool, then the line 'It's a new day' is squeezed out and again just seems kinda weak. I guess I don't need to point out Orton's opening gambit as Cena did that about a year ago or so.
It's not that I'm against theme music having words in them or anything, but when the writing is so obvious and on the nose it makes me cringe. HHH's Game theme is a classic even though it is playing on his nickname, but it's made up for by his slow amble to the ring then the spitting of water at the right time.

Anyways, that's what I'm thinking
