根据提供的歌曲歌词，检查歌曲是否包含特定的单词或短语。 
歌曲歌词： 
I got my peaches out in Georgia (oh, yeah, shit) 
I get my weed from California (that's that shit)
可以使用字符串搜索算法检查歌词中是否包含特定的单词或短语。例如，在Python中，可以使用`in`操作符检查字符串是否包含指定的子字符串，例如：

```
lyrics = "I got my peaches out in Georgia (oh, yeah, shit)
I get my weed from California (that's that shit)"
if "peaches" in lyrics:
    print("This song contains the word peaches!")
if "weed from California" in lyrics:
    print("This song mentions getting weed from California!")
```

这将输出：

```
This song contains the word peaches!
This song mentions getting weed from California!
```

请注意，如果使用字符串搜索算法，需要区分单词和短语的大小写和拼写。
