Only hearing half the song cos it's playing in the other room

I don't listen to the radio much, and have little or no knowledge of the current chart climate, preferring to listen to my own cds. I work in a small office that has a warehouse downstairs. You can see into the warehouse fromt he office window and hear almost everything that goes on in there.

Normally the guys who work there bring their own cds in to play while they work but lately I think the CD player must have become broken as they seem to be playing the radio an awful lot. Now, is it me or do they really only repeat the same five songs ad infinitum? It's more than a body can stand!

So anyway, I've become quite used to these five songs though I'm not sure what they are or who they're by. The funny thing is, because I am hearing them through a thin wall I only get half the frequencies. When I go downstairs into the warehouse, the songs sound totally different.

So these 6 songs:

One of them is quiet for a bit and then goes "I've bin wankiiiinnng! I've bin wankiiiinnnggg!" it's quite tedious. My brother was watching it on MTV just now and it did sound different to the filtered version - but not better.

Then there's one that fucked me off for ages that I later found out was Britney's new single. All I hear through the wall is this "eeeeeeEEEEEEEeeeeuuuh" thing that sounds like a horrible banshee wail. It echoes all over the warehouse for added creepiness.

Another one sounds like Liam Gallagher or Chris Evans going "Wummeeee serraaahhh wummeee wummeee serraaaahh wummeee" to some lame indie music. I don't know what it is and I'd rather not hear it ever again.

This is what old people must feel like when their hearing goes bad and all music sounds horrible.
