Attend 43 Different Concerts

In order to be more educated in the arts, I have set this goal. I feel it is important to see different types of music and art as one grows older while Rachael also thinks it helps to see Steven Tyler once every couple years. In order to reach my goal of 43 different concerts I have set forth a few rules—
1) One concert with two popular musicians from different bands will count as two concerts,
2) Multiple concerts from the same artist at different times will count as one concert each,
3) Boy-band concerts will count as ten concerts each (just kidding, but see Rule #4 below),
4) The reader of this goal is only allowed to make fun of me three times regarding attendance of a boy-band concert, and
5) Concerts I do not remember but still attended will count towards the total as I must only be physically present and not mentally.
Following are the concerts I have already attended, in no particular order:

1. Blink-182
2. MxPx
3. N-Sync
4. Sting
5. James Taylor
6. Backstreet Boys
7. Tool
8. The Eagles
9. Don Henley
10. Aerosmith
11. Bryan Adams
12. Annie Lennox
13. Authority Zero
14. Rooney
15. Bad Religion
16. Chronic Future
17. Dexter Freebish
18. The Flaming Lips
19. Flogging Molly
20. Hoobastank

I’m halfway there!!
