My brother the music fan

My brother is a big music fan. I do enjoy music, but not to the level of my brother. He stores music in his phone and plays it whenever he can. He collects guitars, buying some he fancies and selling some of them when needed. He actually has Fender Amps in his room. When he tells me that he got a good deal for some music gadget, I guess my eyes glaze over a bit because I really don't understand them, I do not know what is supposed to be a good price for them and what's a good quality for them. He talks about certain bands that I do not know of. I do like the song selections he plays whenever I ride in the car with him, but then I'm not that particular, as long as it sounds nice I'm ok.  To each his own, I guess :).
