I have a KZ ZSN Pro IEM and it's been going strong for 4+ years.

I also have a cheap Bluetooth QCY IEM that I use for podcasts and when I don't want wires tangling me.

Whenever I change from the Bluetooth QCY to the wired KZ I am in awe. The KZ ZSN Pro is a blast to listen to. Specially metal. The definition, the sound of the bass drums, everything is clear and powerful.

So I decided to try some entry level open back headphones and bought the SHP9500 that was cheap on Aliexpress recently. I thought I would find it even better since a lot of people sang it's praise for the price, but I am underwhelmed.

I find my KZ to have way more definition and power.

Also I need to up the volume of my smartphone quite a bit compared to the IEMs. It is near max volume.

Of course they are different beasts and the IEMs are literally inside my head. I don't really know what I expected.

I'm sure beyerdinamic or other more expensive brands might be better, but I don't feel like going down that path.

I'm going to keep the SHP9500 for a week more to see if I like it for different situations, but for now I am not amused.

I noticed that Tildes has had no previous discussion of Andrew Hickey's wonderful music podcast A History of Rock Music in 500 Songs. So I thought I'd write a little about it, in case it might bring as much joy to someone here as it has brought me. It's easily my favourite podcast, and it might actually be my favourite work on music history in any medium. It's really that good.

The podcast started something like six years ago, and like its name suggests, it presents a history of rock music. But not just the "four white guys and some guitars" rock music of the 1970s and beyond, but a far more in-depth exploration of where the genre came from and how it has evolved. This is not one of those podcasts where a host or hosts have chosen a topic, done some light resarch and then talk about what comes to their mind. Instead, each episode is thoroughly researched, pre-written and edited. It is a high quality audio lecture delivered by an excellent and witty storyteller who knows what he is talking about.

The first episode was on "Flying Home" by the Benny Goodman Sextet, a jazz and jump blues track released in 1939, and therefore naturally not really a rock song, but something that works as a good starting point in the wider discussion of the genre's evolution. From there, episode by episode, Hickey has told us about the (or rather "a") history of rock music chronologically, taking us through the 40s and 50s, and currently heading towards the end of the 60s. He has indicated that just as 1939 was a somewhat arbitrary starting point, his 500-song history will end with a song that was released in 1999. Looking at his current pace, it may be a while until we get there.

The latest episode is song #174, "I Heard it Through the Grapevine", first released in 1967. It's part one of a two-part narration, with the current episode concentrating on the song's early history and its writers Norman Whitfield and Barrett Strong, while the upcoming episode two will look at Marvin Gaye's version and career at that point.

Hickey has in fact recently started to split some songs into multiple episodes, and he did it also with the previous song, song #173, Bob Dylan's "All Along the Watchtower", first released in 1967. That one had Part 1 that concentrated on Dylan's version, and then Part 2 that covered Jimi Hendrix's version. Although, when I say that those episodes concentrate on Dylan's and Hendrix's versions of the song, that's not exactly true. It would be more accurate to say that Part 1 concentrates on Dylan's career in the late 60s, as well some related subjects and artists from the era, while Part 2 looked at Hendrix's career at the time, as well as subjects and artists related to him around that time.

And this is actually an important point to make. While the episodes certainly tell you a lot about the song that they are discussing, they are not solely about the song in question, and they never really aim to give you a subjective interpretation of the song or anything like that. Instead, you are given plenty of historical facts, you hear a lot of interesting stories, and you find out how the song and the people who were involved with it fit into a larger narrative of rock music. And you also get to hear excerpts of some really good music along the way. Hickey is very much an expert in the topic, a great storyteller, and seems like someone who knows how to do his research.

The podcast's early episodes were shorter, about half an hour or so, while some of the more recent episodes have become much longer, some reaching over four hours, which is the reason why Hickey has started to split some episodes into multiple parts. In addition to the main podcast, there are also Patreon bonus episodes which are not part of the main narrative, but which I can highly recommend. They function as companion pieces to the main story, and typically last between 10 to 30 minutes; for instance, the bonus episode for the first "I Heard it Through the Grapevine" episode was on the song "Bend Me, Shape Me" by Amen Corner. And so, although he is officially just at song #174, Hickey has probably covered well over three hundred songs so far.

The podcasts are free of ads and fully community supported. You should be able to find the podcast on all the main podcast providers, and it has a dedicated website at 500songs.com. If you don't know where to start, the double episode on "All Along the Watchtower" that I mentioned earlier could be a good way to check if the podcast is for you. Or, if you have some favourite artists or songs from the 40s, 50s or 60s, check out the tags on the website to see if he has made episodes on them. Or you can of course just start from the beginning, like I did.

Last year, Hickey was also a guest on Rick Rubin's podcast, and that interview could also be a good introduction to Hickey and his work.
