I used to be a fanatic. I used to collect everything they released from Singles to Vinyl to DVD to Posters, Books, Calendars, etc. Then it got too expensive, and I grew up. I'm now just a fan. I still buy the remasters, but I no longer collect everything. I've eliminated most of my bootlegs and concert recordings. I don't buy singles, and don't even try too hard to get to their concerts. I'm 37 and was fanatical about U2 from '92 to 2005.
Actually, I'm not fanatical about any band anymore. U2 was my only true love or obsession when it came to music. Now I'm just a fan of many bands and artists.
