Choices between CD's depends on personal prejudices. It is often easier to buy something close to the music we already like, instead of buying something way different and get use to it. When I go to the shop I usually listen to the music first, and I have usually preset my mind on a certain genre. The reason I write reviews is only to inspire people to take a look at the CD, and listen to the previews that often can be found on label-sites
Personally I like all sorts of music, but I prefer to listen to techno in all genres, and by psychedelicplanet.com I mean to make the psychedelic culture more visible. I also hope to inspire some of those who haven’t set their mind up for something special, and perhaps those who normally don't listen to this sort of music, and therefore don’t know what to look for.
You’re right that we can’t buy all the music we see and we can hardly prelisten to I all. Therefore I think my reviews can be a better help than to make decisions only by looking at the cover.
